Microsoft Natural Keyboard?
You may need to re-boot; and go and download Inteli-type software. The native drivers in WinXP sometimes get messed up running Microsoft keyboards (which makes absolutely ZERO sense, but it happened to me).
Just pop over to your keyboard's support site, and download and install your latest Keyboard driver and software suite.
