I'm using one of the profiles for Battlefront 2 that I found in these forums and I'm having an odd problem with the mouse. My crosshairs want to slowly move upwards until I'm aiming at the celling. I can pull the crosshairs back down but it still wants to move upwards. It makes the game very difficult to play. I have the same problem with any profile I use so I doubt that is the problem. I am using a Logitech MK530 keyboard/mouse bundle. I was curious if anyone else has run into this problem? Thanks!
