I don't remember it being like this yesterday, but today I fired up HL2 and my trackball is slow as heck in the menu. It's moving like molasses, I have to spin the ball 4-5 full rotations just to make it across the screen (on the desktop 1 rotation does the job). It also seems slow in game, jacking up the acceleration helps ingame but I think the game is affected in a similar way. Trackball works fine in all other games and on the desktop.
