When playing UT2k3, the game abruptly sends me back to my desktop. The game is still running, just minimized and I can click UT on the taskbar and get back into the game. It is just annoying!

I have Windows XP home edition, Athlon XP 2500, 512MB DDR, and an AOpen motherboard. I have the patch 2225v downloaded and it still does this.

Any suggestions?
