Hey so I seem to have an issue where I cannot use any form of mouse input (either through my mouse, track pad or touch screen) and the game acts as though I am holding down the attack button. does anyone know a way around this?

Dark Forces, or Jedi Knight?

Jedi Knight.

First thing I would try is to ensure that you don't have joystick enabled. Do you have a joystick/gamepad plugged in?

I am getting this problem too. I have no idea what's causing it, I only have a mouse and keyboard, no joystick.

edit - I deleted every single rebind in the game and then added the mouse rebinds manually one by one, it was still causing the issue. I put them on maximum sensitivity and map directly to value but it was still broken - I just restarted my PC and it cleared it and I can now move and shoot! Try restarting if you still get this problem.
