I'm basically borrowing a Ninox Aurora to test it out. I'm using an Overclockers MegaMat XXL (which covers my entire desk) and I had no problems what so ever with my Zowie FK1.

When I flick around in games like TF2 or Quake it will very often look directly up. This happens so much it's almost unplayable. I can flick just to turn a little bit (not even necessarily that quickly or long distance) and it'll look straight up or sometimes down.

It's really annoying when I'm trying to rocket jump or something like that. Does anyone have any idea what could be causing it? Am I missing a vital step that helps the mouse work correctly or is this a common thing? Thanks for any help.
