Here's a weird one. I recently installed a new mouse and with it, Logitech's Set Point software. The mouse is great (MX Revolution), but it seems to be conflicting with some games, notably FO 2!! If I switch it off the game runs, if it's loaded, the game won't load!! Does anyone have any ideas about this. I'm running XP64 on an AMD dual core system with 2MB RAM(or is that GB, I can never remember) and a 7800GTX.
