I've installed Windows XP via Bootcamp on my 20" iMac and I'm having a small problem. Every now and then the keyboard stops functioning and the only way I can get it to work again is to unplug it and plug it back in. This only happens in Windows and I've only ever had it happen in games. It has happened in a couple of games, however (Civilization 4 and D&D Online). It's not a big problem, I can certainly live with it for the small amount of time that I'm in Windows, I'm just wondering if anyone else has come across this problem?
