no. i check my sensitivity and it increases when it doesn't change. i never change my sensitivity on my mouse or ingame. It just changes by itself but the number doesn't change. It stays at 5 where i keep it. None of the numbers change, only when i go switch back to trem is when it changes.
scenario: I play trem. Then i'm like let me go check aim. so i minimize tremulous ( i play in fullscreen) by pressing the windows button. trem goes down and i click on aim and talk to some peeps. i go back to tremulous by clicking it on the taskbar on the bottom (windows vista sp1). i move around and find that my sensitivity has increased by a LOT!. Like 3 folds. I check my sensitivity ingame, its the same; i check my dpi, its the same. But my sensitivity has increased.
I don't know why this happens, but i believe it must a bug or something in vista cus this never happened to me when i was on my old win xp sp1 computer.
