G'day. A bit more research revealed that the disappearing 'tooltips', as they're apparently called, is an ongoing bug with XP and ME, which Microsoft continually ignores. LLXX, I tried the restarting explorer.exe thing last night and it seemed to work, but I've also followed your tip about keeping the Taskbar on top of other windows, so I'll see what happens. Ctrl-X, I don't know whether I want to mess about with video drivers etc because, frankly, I don't know what I'm doing in that regard (besides, my computer's still only about six months old). And I tried the F11 thing, but found that the best way to get around this issue was to resize the windows and not hit that Maximise button (the middle one in the top right corner). So if that works (which it does) I'll just use that, I think. I thank you both for your help. Regards, scoopyx.
