predcon: I'm having a little trouble with phantom mouse movements in the menus. It's mostly horizontal. Like, if I press the up or down arrow keys while on the options menu, the volume and detail settings will rapidly cycle to the right. It's a laser mouse, and I'm not sure how sensitive the menus are to mouse movements. Apart from unplugging the mouse entirely when I play, I don't know what to do.
korell: Do you have any game controllers connected at all?
A Logitech ChillStream that comes with X360 drivers. And I used to have custom PS3 controller software, but I think that got wiped clean in a System Restore. Lemme unplug the X360 and play it again, and I'll edit this post with the results.
[EDIT]
Yup. That dunnit. I even looked at the Joystick calibration option in the Control Panel (Windows' Control Panel, not Tyrian's), and the left A-Stick was fluxing a bit around the center.
