Well, we managed to start a chat where we both had our cams on the other day. I started mine first, then she started hers. Unfortunately the fun lasted for only two minutes; then her cam froze again.
Next time I see her I'll ask if she can do that PC Diagnostics test. That's a good idea, I hadn't thought of that

Thanks.
Her computer can (or should be able to) run Windows XP since we checked the system requirements, so if that test doesn't reveal any problems, she might buy a WinXP upgrade to see if it's because of Windows 98 -- you know 98 isn't the most stable version of Windows [:P] -- but I'm afraid she'll need a brand new PC, even if WinXP will run correctly (that'd be a waste of the XP upgrade too).
By the way, I'm connected through DSL (1536 down - 256 up), she uses dial-up. It can't be her connection speed as we can run both cams without problems if she uses MSN Messenger and I use Yahoo! Messenger. We tried with her using Yahoo! Messenger and me using MSN Messenger, but Yahoo! Messenger freezes when she tries to set up the webcam -- another reason why I think it's her computer.
Last thing we've noticed: she can't move too fast or the cam will freeze. So if she has to get a CD or answer the door, it's almost certain the cam will stop working the second she stands up. It's a brand new QuickCam Messenger, so it can't be the cam that's causing the problems.
By the way, nice smilies
