I just did a fresh install of KOTOR 2 and I having the problem of the inputs on the main menu freaking out. When I select new game, on the character selection screen the highlight keeps moving to the right constantly, even though I'm not touching anything. I try to change the settings to fix it, but it's even worse there, the sliders keep moving on their own especially the brightness slider, and whenever I try to change the resolution the game will crash.

Is this an issue with the Steam version? How can I fix it?
