hey people im havin trouble w/ my mouse on halo pc. it was working fine till a few days ago when i get in the game and its like im constantly moving it to the left so my guy spins. also when i go to options if theres different options in a horizontal row, it still circles to the left...i took out the batteries (its a cordless mouse) and used the arrows to get it to options and it still did it even tho the mouse wasnt sending a signal. any1 noe what i should do? any help would be much appreciated. thx!
