This problem just popped up about a week ago, and has been plaguing me ever since. It seems that whenever I run a game that uses D3D and/or 3dfx, my mouse will crash in game, being completely useless. At which point I exit the game, and my mouse still does not function untill I reboot my machine. I've tried using the manufacturers drivers as well as the latest intellipoint drivers, but nothing helps. Anyone ever had this problem before? Or anyone want to confirm my thoughts that the damn thing is broken within its first 2 months of use?
