Microsoft tells me they don’t plan to issue a “recommended” hardware configuration for Windows 7, because the company believes there are too many varied uses to cover, and that any such statement would be too complex. The company also claims its minimum requirements have proved “generous” enough to cover most cases during the year of widespread testing of pre-release versions.

The minimum required hardware for Windows 7 is as follows: a 1 gigahertz or faster 32-bit or 64-bit processor; 1 gigabyte of memory for the 32-bit version of Windows 7 or 2 GB for the 64-bit version; and 16 GB of available hard disk space for 32-bit or 20 GB for 64-bit. In addition, Windows 7 will require a graphics card or integrated graphics chip that is compatible with at least Microsoft’s DirectX 9 graphics system and at least the 1.0 version of its graphics driver standard called WDDM (Windows Display Driver Model).

More details are at: windows.microsoft.com/systemrequirements. I would suggest at least doubling the memory Microsoft recommends, not because I believe the company is lying, but to give yourself some headroom as your needs and interests grow.

I have used Mac laptops for the past 15 years, and am in the market for a new machine. When it comes to computers, I’m not “the sharpest knife in the drawer,” and I only use my laptop for very simple, basic tasks. What new laptop would you recommend? I do not desire or need exceptional file storage, graphic capability or any other esoteric spec.

You could get a cheap, small Windows laptop called a netbook, which would meet your simple needs. Acer, Asus, Lenovo and others make good ones. But I’m not sure that’s the best choice for you, given your self-description. If you’re a longtime Mac user, and you are used to the Mac, I’d suggest you consider sticking with it, because any netbook would require you to learn a new operating system and new software, even for simple tasks. Mac laptops are excellent machines, with a great operating system and built-in software. The only negative is cost, which you didn’t mention as a criterion. Apple doesn’t make bargain laptops. The cheapest Mac laptop, at $999, costs about triple what you could pay for a netbook.

I would like to change my Internet Service Provider (ISP), but fear doing so, since the task of informing all my email contacts of the new address seems grossly laborious. Are you aware of any utility available that will perform this task accurately?

The only one I ever tested is called TrueSwitch, and is available at trueswitch.com. It is a service that copies all your email, address books, calendar entries and bookmarks from the old ISP to the new one; notifies everyone in your address book of your new email address; and even forwards email from your old address to your new one for 30 days. It costs $20, but is free if you are switching to certain services, including Yahoo or Comcast.

One caveat: My test of TrueSwitch occurred five years ago, and, while it worked well then, I can’t be certain that it still does.

Here are a few questions about computers I’ve received recently from people like you, and my answers. I have edited and restated the questions a bit, for readability.

I switched from PC to Mac a year ago, but now I am thinking of adding a Windows laptop. If I do, what kind of compatibility problem would I have? I would be using the laptop mostly to write, to send/receive email and to Web browse.

In the old days, there were compatibility problems, but most of those have gone away. Based on your simple predicted usage, I’d say that you should be fine. For instance, both Macs and PCs can interchangeably open and edit all of the major file types — JPG pictures, MP3 music, Microsoft Office documents, Adobe PDF files, etc. Email and instant messages can, of course, be exchanged between the two platforms, even if you are using different programs. And Macs understand Windows file extensions. Also, you can use both platforms simultaneously on the same home network to access the Internet.

In some cases, you might need different programs to open the same files on the two platforms. But even that obstacle has greatly diminished. For instance, programs like the Firefox and Safari Web browsers, Adobe Reader, iTunes, Microsoft Office, Google Earth, Picasa, Photoshop and many others come in native versions for both platforms that can handle the same files. And, of course, Web-based programs like Gmail and Yahoo Mail work on both. Sometimes, the same programs have different features and user interfaces on Windows and Macs, but I haven’t found these differences hard to master.

The biggest problems for average users are Quicken, whose Mac version is inferior and incompatible; Internet Explorer, which is no longer made for the Mac; and Microsoft Outlook, which is replaced on the Mac by a program called Entourage that is similar but uses a different file format. And networking can be tricky. In general, the Mac does a better job of seeing Windows PCs on a network than Windows does of seeing Macs.

I use Outlook Express for my email, and I store a lot of mail in local folders. Is there a simple way to back these up? If I buy a new computer, can they be transferred?

Yes. There are two methods. One is a manual method, which Microsoft explains in a detailed document at this Web site: support.microsoft.com/kb/270670.

The other, quicker, method is to obtain one of several utility programs that can back up your Outlook Express data and, in some cases, allow you to transfer it to another PC. I haven’t tested these in years, and thus can’t recommend one over another. But one example is a free program called Outlook Express Backup, which can be found at genie-soft.com/products/oeb. Another is a $40 program called Outlook Express Backup Wizard, which can be found at: outlook-express-backup.com.

Do you know of an iPhone GPS application that speaks directions? It would make the iPhone similar to a TomTom or Garvin GPS unit.

A: No, but Apple recently announced that, under its new 3.0 operating system for the iPhone, such programs will be possible. Several companies are believed to be working on them, and I expect them to be available later in the year. The reason none exist yet is partly legal, having to do with the licensing of the underlying maps.

Do you still recommend the Dell XPS One all-in-one computer that you favorably reviewed last December? I am not a techie at all but need to replace my 5-year-old Dell and was interested in an all-in-one.

Yes. In fact, I now own two of these Dell XPS Ones and use them as my Vista desktop computers, at home and in the office. I still believe, as I wrote in my review, that this Dell’s hardware is superior to that of the competing Apple iMac, though the Vista operating system is inferior to Apple’s. And the base XPS One now costs the same as the base iMac — $1,199 — instead of $300 more, as it did last year. So, if you want the Windows operating system, and like the look and convenience of an all-in-one desktop, I still favor the XPS One. You can find my review at tinyurl.com/2xw 6mv.

Will Apple’s new MacBooks and MacBook Pros run Windows directly without an intervening “virtual machine” program like Parallels or Fusion?

Yes. All Apple Macs running the current Leopard operating system, including the new laptops, come with the ability to directly run Windows XP or Vista. Using Apple’s built-in “Boot Camp” feature, you can start up the computer in Windows, instead of the Mac’s own operating system, which turns the Mac into a pure Windows machine, with no trace of the Mac operating system running. The upsides of this approach are maximum Windows speed, and compatibility with the most graphics-intensive Windows programs, including games. Note that, to run Windows on a Mac, you must obtain and install a fresh, boxed, full version of XP or Vista. Apple doesn’t supply Windows.

I have a Yahoo email account, and wonder if Yahoo allows receipt and storage of email directly via a computer email program, such as Outlook, or is it all Web storage? Can you do both?

Yes. Yahoo offers a “Plus” option, for $20 a year, that permits users to receive and store their Yahoo email using a locally installed, instead of Web-based, email program. This approach does work with Microsoft Office, as well as many other local email programs. And you can still use Yahoo’s Web-based email interface at the same time. The Plus option also includes other benefits, including the elimination of ads and a doubling of the size limit on individual messages, to 20 megabytes.

After reading your positive review, I downloaded Firefox 3.0, only to discover that some of my favorite add-ons, including a search toolbar, are incompatible. What can I do about this?

Wait. As I noted in the review, when major new versions of Firefox come out, it takes a while for some of the many add-ons for the browser to be updated so they are compatible with the new version. Because these are written by a very large number of different companies and individuals, the process will be gradual, and some will be updated more quickly than others.

As for search toolbars, like those from Google (GOOG) and Yahoo (YHOO), I doubt that most people still need them. When they first came out, these toolbars provided things the top browsers lacked: a permanent search box, pop-up blocking and a few other useful features. But all the major browsers now provide these things without requiring the installation of any external toolbar. The companies that make the toolbars can use them to sell advertising or attract you to their search engines. But, for many users today, they are redundant.

I don’t want to run antivirus software constantly, but I would like to periodically run a program that could scan my computer and remove viruses and the like. Does such a program exist?

Yes. Here’s one example. Microsoft (MSFT) makes a small, free program called the Malicious Software Removal Tool that looks for, and tries to remove, a limited number of the worst examples of malicious software. It can be downloaded at www.microsoft.com/security/malwareremove.

However, this isn’t a comprehensive antivirus program. Microsoft says it detects and removes only “specific, prevalent malicious software,” and advises that “You should also use up-to-date antivirus software to help protect your computer from other malicious software.”

I am in the market for a laptop. I was considering a Dell (DELL) or an H-P (HPQ) but have learned that Apples now run Windows. I have financial (Quicken) and other business files (Excel, Word and PowerPoint) that would need to be transferred to the new computer. Would this be possible on an Apple (AAPL)?

Yes, in the same ways you could transfer files from one Windows PC to another. For example, you could burn them to a CD or DVD, copy them to an external USB drive, or transfer them over a network or via the Internet. In fact, if you buy your Mac at an Apple retail store, the store’s staff will move your files over free, or for a modest fee, depending on which folders, and how many, you want transferred.

Once the files are on the Mac, you can either use native Mac programs to read and/or modify them, or you can install Windows and run your usual Windows programs to handle the files.

For instance, even if you never installed Windows on an Apple, your Excel, Word and PowerPoint files could be used in the Mac version of Microsoft Office. However, the Mac version of Quicken isn’t as compatible with the Windows version’s files. So, for Quicken, I suggest installing Windows on the Mac and running the Windows version of Quicken.

Here are a few questions about computers I’ve received recently from people like you, and my answers. I have edited and restated the questions a bit, for readability.

I am going to start college in the fall and I need a laptop. Uncle Jim, who is a Mac addict, is making an argument for a MacBook with Parallels 3.0 and Windows XP installed. He said that way I would have the best of both worlds. My mom is looking at the price. She said we could get a PC for less money but I want to make sure we’re making the right decision. If money is not an issue, what is your recommendation?

Both your mom and your uncle are correct. You can indeed get a decent laptop from Dell or Hewlett-Packard for less than the $1,099 that Apple’s least expensive Mac laptop, the MacBook, costs. But, in my view, the Mac has a better, faster operating system, better built-in software, and is far less likely to expose you to viruses and other malicious software. Plus, the MacBook itself is a sturdy piece of hardware. And there’s a very good Mac version of Microsoft Office that is fully compatible with files created on the Windows version.

Your uncle is also correct that Macs can run Windows, and Windows software, quite well. However, the solution he suggests, using the Parallels software, which enables Windows use on a Mac, will add significantly to the price. Parallels costs around $60, and you also must buy a full, boxed edition of Windows XP or Vista. While prices for Windows vary, this full version (not an upgrade version) of XP can cost nearly $200, and Vista typically costs more.

So, if money really isn’t an issue, I recommend the MacBook. But, since that is rarely the case in real life, you might want to weigh the cheaper alternatives more carefully. Or, if you do buy the MacBook, I’d hold off on the Windows installation until and unless you find you need Windows programs that have no counterpart on the Mac. The average undergraduate likely won’t.

I am dissatisfied with my Internet service provider and I would like to switch to another one. If I switch, can I keep the same email address? Do I have to keep paying the old ISP if I switch and keep the email address?

It depends on your ISP. If it is America Online, you will be able to drop AOL as your ISP and continue to use your aol.com address, regardless of which provider you use to access the Internet. But, in most cases, if you are using the email address provided by your ISP, you will have to relinquish it. However, I would suggest you consider obtaining an email account that isn’t tied to an ISP, so that, if you have to change ISPs again, it won’t disrupt your email. Among such email-only services are Yahoo Mail, Microsoft’s Windows Live Hotmail, and Google’s Gmail.

Your column last week concerned a navigation device called Dash Express that transmits the speed and location of your car to the company for traffic information purposes. But couldn’t this capability also be misused by the company to track a driver’s whereabouts, or even help issue speeding tickets?

Theoretically, yes. But the company, Dash Navigation, says it retains no personally identifiable information on its servers, and merely collects traffic data from participating cars anonymously. A company spokeswoman says: “If the FBI came in and asked us to find someone, we would have no way of locating an individual car.”

Here are a few questions about computers I’ve received recently from people like you, and my answers. I have edited and restated the questions a bit, for readability. This week my mailbox contained questions about using an iPhone overseas for data purposes, running Microsoft Office 2000 on Vista and using broadband-provider email in two locations.

You recently wrote that iPhone owners using the device overseas must roam on AT&T at high rates, because the iPhone won’t work with SIM cards from foreign carriers. You noted that AT&T has a monthly plan that cuts these per-call voice rates somewhat. But what are the options for using an iPhone overseas for data purposes, such as email and Internet browsing?

Until Apple initiates iPhone service with foreign carriers, which is expected to be a gradual process that will begin in Europe, iPhone owners traveling abroad will be forced to roam on AT&T and to pay through the nose for data as well as voice calls made over cellular-phone networks. They won’t be able to buy cheaper service from a local foreign carrier and enable it by simply replacing the phone’s AT&T SIM card with the local carrier’s.

In addition, it is important to note that, even if you are willing to swallow these huge voice-and-data rates, you must call AT&T (formerly Cingular) before you leave the U.S. with your iPhone (or any AT&T phone) to modify, or “provision,” your calling plan so it will even work overseas.

Here are the details. Note that these prices and plans apply to many other phones AT&T sells, not just the iPhone.

To recap the voice-calling situation, AT&T charges very high fees, which can be mitigated a bit by adding a special $5.99 monthly add-on feature, called AT&T World Traveler, to their plans. This voice feature allows you to roam in 190 countries and gives you discounts on calls from 80 countries. For instance, in France, Italy, Germany, and Britain, you pay a still-high 99 cents a minute, compared with an even worse $1.29 without the plan. In Hong Kong or Israel, you pay a whopping $1.99 a minute, instead of an even more outrageous $2.29 or $2.49, respectively, a minute.

For email and the Web, the best bet for iPhone owners is to avoid using cellular networks and employ the phone’s Wi-Fi capability, which can cost nothing extra. Try to find a free or reasonably priced Wi-Fi hot spot in which to check email and do Web browsing. You may even be able to make cheap voice calls this way using Internet-based calling services like JaJah (mobile.jajah.com) which, in my domestic tests, worked properly via the iPhone’s Web browser.

However, if you need to check email constantly or frequently, you are unlikely to be able to depend solely on the Wi-Fi method. You can rely on AT&T roaming to do this over foreign cellular services, but, as with the voice call situation, it will cost a fortune.

AT&T offers an add-on plan for $24.99 a month, called the “PDA/Smartphone/iPhone International Data Plan.” This is on top of the $5.99-a-month voice plan, and is also additive to the $20 a month for unlimited data when in the U.S. that is built into your base plan. But it isn’t unlimited. You get only 20 megabytes of overseas data use a month, and pay a stiff $.005 a kilobyte for all data use above that.

Plus, this international-data plan only works in 29 countries. Outside those countries, the cost is an astounding $.0195 a kilobyte, or roughly $20 a megabyte. To put that in perspective, a single email with a medium-resolution picture attached could amount to a megabyte. More information is at www.att.com/wirelessinternational.

One more note: apparently AT&T can and will cancel your roaming service overseas if it notices what it considers an unusually high number of calls being made. One reader with an iPhone reported that, after arranging belatedly in Europe to get the voice-roaming service, he was suddenly cut off when he reached India, with AT&T explaining the cutoff as an attempt to prevent suspected fraud.

According to this reader, AT&T said he had been cut off “because there were ‘too many calls from India and other countries’ and they did not think it was possible anyone could be doing that for real, so to protect me, they cancelled the service.” An AT&T spokesman says the company can’t comment on the details of this particular case without knowing the traveler’s phone number.

You say Office 2003 runs OK on Windows Vista. I have been using Office 2000 and it does everything I need. Will it also run OK on Vista?

Microsoft doesn’t officially support Office 2000 on Vista. It may work, but I haven’t tested it.

Is there a way that I can use my same email address both at my home in New Jersey and at my winter place in Florida, even though I have broadband Internet service in New Jersey but am limited to dial-up Internet access from a different provider in Florida?

Some broadband providers also make available a supplementary dial-up service for their customers, which may be free or cost extra. Check with your broadband service to see if it offers this option.

If not, you could simply use an email account that isn’t necessarily tied to an access provider at all, such as Web-based email services from Yahoo, Google or Microsoft. You could switch to one of these permanently, and use it in both locations, or you can forward your main email address to one of them while you are in Florida. People who send you email wouldn’t have to learn a new address and many Web-based services allow you to set your main address as the “reply-to” address for emails you send.

Here are a few questions about computers I’ve received recently from people like you, and my answers. I have edited and restated the questions a bit, for readability. This week my mailbox contained questions about switching to a Web-based email service, viewing PDF files on Macs and antivirus programs that support Windows ME.

Q: I use an email address provided by my Internet service provider and access my email using Microsoft Outlook. I would like a more portable email address that isn’t tied to any one ISP, and an email program that is independent of any particular computer. What can you suggest?

The obvious answer is a Web-based email service that has a decent Web-based interface that can be accessed from any computer. There are lots of these, including Yahoo Mail, Microsoft’s Windows Live Mail (formerly Hotmail) and Google’s Gmail. I am not a fan of Gmail, which I believe has too many quirks and too few options for users to avoid them. Windows Live Mail is promising, but my favorite among these leading services is Yahoo Mail.

Q: I am thinking of switching to Apple, but I am wondering if Macs come with free Adobe Reader software, like some Windows computers do.

No, Macs don’t include Adobe Reader, which allows the viewing of PDF documents — but they don’t need it. The Mac operating system allows you to open and create PDF documents, right out of the box, without any additional software. If you get a PDF file as an email attachment, you can just double-click it and it opens. Even better, any program running on the Mac can save almost anything as a PDF file. For instance, you can save a Web page as a PDF file that can be opened in Adobe Reader on Windows. Adobe charges money for software that does that.

However, if you prefer Adobe Reader, there is a free Mac version, very similar to the Windows version, that you can download at www.adobe.com.

Q: Do you know of any antivirus programs that are continuing to support Windows ME in their newest versions?

The latest version of Grisoft’s very good AVG Anti-Virus program still works with the ancient Windows ME operating system, according to the company’s Web site, at www.grisoft.com.

Q: Last week, in answering a question about the speakerphone function on another Windows Mobile phone, you claimed that, on the Motorola Q, a multistep software process is needed to turn on the speakerphone. But isn’t that wrong? Isn’t there a hardware button that does that?

Yes, I erred when I wrote that. I just blanked on the hardware button, which I certainly knew about, having carried a Q for a couple of weeks while testing it. We have already run a formal correction, and I hereby apologize to Motorola for implying that the process was clumsy, when it’s simple.

Here are a few questions about computers I’ve received recently from people like you, and my answers. I have edited and restated the questions a bit, for readability. This week my mailbox contained questions about transferring “Favorites” from your laptop to your desktop and converting copy-protected WMA files to play on an iPod.

If you have a question, send it to me at mossberg@wsj.com, and I may select it to be answered here in Mossberg’s Mailbox.

Q: Can you tell me how to transfer the Internet Explorer “Favorite” Web site addresses from my laptop computer to my desktop computer? Both computers are Windows XP.

Just go to the “Import and Export” command in the File menu of Internet Explorer on the laptop — the machine with the Favorites you want to copy. Select “Export Favorites,” and follow the prompts to save your Favorites as a file. You can name it anything you like, and I suggest you save it to your desktop or some other place where you can find it quickly.

Next, copy this file to the desktop computer — the one you want to populate with your Favorites. In Internet Explorer on this second computer, again click on “Import and Export” in the File menu, only this time, select “Import Favorites.” Specify the file you copied over from the first computer, and all the Favorites it contains should now be on the second machine.

Q: In your recent review of the new Apple iMac that uses Intel chips, you briefly said it couldn’t run the Windows operating system out of the box. Can you elaborate on why that is, and whether Windows will be able to run on this computer eventually?

Apple is now using the same chips in this Macintosh that are used in Windows computers, and it says it won’t do anything to stop people from running Windows on these machines. But you can’t just go to the store, buy a copy of Windows XP, and install it on these new Macs.

That’s because Apple is using some advanced hardware, besides the Intel chips, that differs from what’s typical on Windows machines. This hardware, which helps the computer to start up, is called EFI and is approved by Intel. But it isn’t recognized by Windows XP. Microsoft says the forthcoming new version of Windows, called Vista, will recognize the new EFI start-up hardware when it comes out later this year. But nobody is guaranteeing that Vista will run out of the box on the Intel-based Macs, as there may be other peculiarities of the new Macs that it can’t handle.

In addition, Microsoft’s Virtual PC product, which allowed Windows to run — slowly — on the old Macs by mimicking an Intel chip, doesn’t work on the new machines. It would seem that such a program shouldn’t be necessary on the Intel-based Macs, or at least should be simple to create. But Microsoft says revising it for the new machines would be a big, time-consuming job.

However, I wouldn’t be surprised to see some other company come up with an add-on product that would allow the new Intel-based Macs to run Windows, or Windows programs, at fast speeds, long before the arrival of Vista or any new version of Virtual PC.

With such a product, you might be able to choose to start up an Intel-based Mac in either Windows or the Mac operating system; or run Windows in a window inside the Mac operating system; or run Windows programs in the Mac operating system, without running Windows itself.

Q: I have purchased a substantial amount of music online through services such as MSN and Yahoo that sell files in the protected WMA format. Is there any way to convert this music so it plays on an iPod?

There is a way, but it’s time-consuming and tedious. You’d have to burn all your copy-protected WMA files (the ones you bought from MSN and Yahoo) to audio CDs — the kind that play in standard CD players — and then re-import them into Apple’s iTunes software as MP3s or nonprotected AAC files, manually filling in the tag information.

The iPod can play MP3 files fine, as well as a number of other formats, like nonprotected AAC files. And iTunes can convert nonprotected WMA files to MP3s for use in the iPod. But iTunes can’t convert copy-protected WMAs, and the iPod can’t play them.

Here are a few questions about computers I’ve received recently from people like you, and my answers. I have edited and restated the questions a bit, for readability. This week my mailbox contained questions about Yahoo’s new Web mail and switching from PC to Mac.

If you have a question, send it to me at I was reviewing. Since both companies are strong in search, it’s no surprise that both have good email search features. You are correct that the search in Gmail is quite good.

However, just as it does in other areas, I believe Yahoo’s latest email search system beats Google’s. A new Yahoo Mail search feature, now gradually rolling out to users of the current Yahoo Mail service, not only searches the text of emails, but also searches within email attachments. In addition, this new search system, which will eventually make it into the test version of Yahoo’s new mail service, can pluck out just the photos from your email, or just the attachments, and display them in search results — something Gmail’s search system can’t do.

As for the folder issue, I am all for the idea that better search will eventually obviate the need for people to laboriously create folders and perfect file names in the computer’s operating system, a task that is a challenge for many mainstream, nontechnical users.

But folders in email programs are different, in my mind. They are easy to create, without any knowledge of the file system, and provide a useful visual metaphor for organizing lots of email. I prefer folders in email programs to Google’s alternative, which isn’t search, but instead a system of labels. This was one of several reasons I cited for why I prefer Yahoo’s new version of its mail service to Gmail.

I am considering switching to a Mac. However, I have hundreds, if not thousands, of dollars of software for my PC. Are the new G5 Macs capable of running PC software?

When you contemplate a switch to the Mac, you have to separate the concept of your data, or files, from the concept of the programs, or software, you currently use to display, edit or play that data on your Windows PC. The Macintosh, out of the box and unmodified, won’t run your current Windows programs. But it will almost certainly handle all of your data using different software or programs designed for the Macintosh. And most of that Macintosh software is free.

For instance, if you have photos on your Windows PC in the common “JPG” format, which almost all digital cameras produce, you may be viewing them in the “My Pictures” folder in Windows, or by using a program like Adobe Photoshop Album. This folder and this program don’t work on the Mac. But, if you copy those pictures to a new Mac, you can view and edit them in iPhoto, an excellent — and free — photo program that comes on every Mac, and which I regard as better than the Windows photo programs in its category.

The Mac doesn’t run the Windows version of Microsoft Office. But all of your Office documents can be viewed and edited, and new ones created, if you buy the Mac version of Microsoft Office. Even if you don’t, the Mac can read and edit Microsoft Word files out of the box. It can also open and create PDF files without downloading or purchasing any software from Adobe.

In fact, for all of the types of files commonly used by mainstream Windows users, the Mac is able to handle them through its own programs that are generally better than their Windows counterparts. And most of these programs, except for Microsoft Office for the Mac, are free on every new Mac.

Still, if you insist on running Windows programs on a Mac, because you strongly prefer them, or there isn’t a Mac equivalent, you can modify a Mac to do so. You do this by buying and installing a $250 program made by Microsoft called Virtual PC for the Mac. It creates a virtual Windows PC inside your Mac that runs alongside the Mac operating system.

However, I don’t recommend relying heavily on Virtual PC for daily use, because it is slower than a regular Windows PC, even on a very fast Mac; and it can also open you up to Windows viruses and spyware that normally have no effect on a Mac.

I recently started using Firefox instead of Microsoft’s Internet Explorer, but have run into a problem with Yahoo Mail. In IE, I get the formatting toolbar when composing an email, but in Firefox I don’t. How do I change this?

Some Web sites have chosen to design features using proprietary Microsoft technologies that aren’t recognized by the standards-setting bodies that strive to make the Web work the same way, no matter which computer or Web browser is being used. Firefox and other Web browsers don’t support these Microsoft technologies, partly because they have been misused by digital criminals to spread viruses and spyware.

This particular feature of Yahoo Mail falls into that category. Yahoo states that the formatting feature in its email composing screen requires Internet Explorer for Windows version 5.5 or above. So, if it is crucial to you, I suggest you revert to Internet Explorer to compose your email in Yahoo, or find an email service that uses industry-wide technologies available on all browsers and computers.

I am not saying that this formatting toolbar in Yahoo is dangerous in and of itself. And I am not saying you can’t use Yahoo Mail with Firefox, or other browsers. You can use it with Firefox, and with Safari on the Macintosh, if you don’t need the formatting toolbar.

Last week, you reviewed and recommended a product called Slingbox that allows you to view the TV signals coming into your home on a Windows PC anywhere in the world. Does the Slingbox record these TV shows for you?

No. The Slingbox, which costs $250 at Best Buy and CompUSA, doesn’t have a hard disk or any recording capability. It merely takes all the programming you would normally get if you were sitting in front of your home TV and pumps it out over the Internet to any Internet-connected Windows PC anywhere that is running the company’s software. All you have to do is log into your home Slingbox remotely using the unique ID number of the box and a password you establish when you install the box at home.

However, while the Slingbox doesn’t include its own video recorder, it does allow you remote access of a TiVo or other digital video recorder, if you have one connected to your TV at home. You can sit in a hotel halfway around the world and not only see shows live on your PC as you would at home, but you can also see shows you have recorded to your TiVo or DVR. In fact, you get the TiVo or DVR menus and program guides right on your remote PC screen and can control the TiVo or DVR just as if you were at home. For more information, see www.slingmedia.com.

In the Outlook Express email program, how can I move messages from one folder to another in such a way that I am always given the choice of which folder they should be moved to?

I can think of three ways to move email messages in Outlook Express that will present a list of destination folders from which you can choose. If you highlight the email message, or messages, you want to move, and then click on “Move to Folder…” in the Edit menu, you should see a choice of destination folders.

The same choice should be presented if you highlight the message(s) in question, press your right mouse button, and select “Move to Folder…” from the menu that appears. And the same list of folder choices should appear if you highlight the message(s) and click on the optional “Move to Folder…” toolbar icon, which is a picture of a yellow folder with a green arrow superimposed upon it.

Because of the volume of e-mail I receive, I can’t routinely answer individual questions by e-mail, or consult on individual problems or purchasing decisions. I read all questions I receive and select three each week to answer in the column.
