I've recently purchased the Humble Bundle V and have been having an absolute riot with the games given. The one problem I'm running into though, is that whenever I launch Psychonauts and run a game, the Camera lists to the right slowly and I can't get it to stop.

Strangely enough when I zoom in (with z), it lists to the left.

I was wondering if anyone else had this problem and if there was a solution. Maybe it's even the mouse configs I currently have on the laptop that interacts strangely with 3D environments.
