Problems with Chopper gunner and tank as well as crashing issue.

Having an issue many others i know notice with the attack chopper gunner seat. When we try to zoom in it pulls way off target in another direction. Also have a problem with tanks just driving by themselves, can be sitting still and it will just starting turning. Not stick drift, there are many people i play with all having same issue. Also on map screen cursor immediately takes off and goes to top left of the screen. Also having crashing issue alot, Not a single round goes thru with out one of our party crashing.
