I just installed Borderlands game (for pc), and everything is fine until i get to the select character screen . The selection never stops moving to the left side, and when i select a character (like a random selection <.<) and the game starts, my view start rotating to the left-up side of the screen and it never stop.

I tried to unplug my mouse to check if that was the problem, but it keeps rotating.

I'm running the game in Windows 7 x64 ultimate edition, with 4gb ram, amd phenom x4 9950, hd 4850 and i cant find the solution for this.

I hope some of you can help me.
