Got the answer:
it's a controller sensitivity issue - your "stick deadzone" is probable too low. This makes the computer/ console super sensitive to the most minute changes in direction of your thumb sticks - even when your not touching it. The system could be picking up on a slight imperfection of the controller design/ manufacture: thumb sticks not perfectly centered.
Here's the fix - access the following menue: Options/ Controles/ Stick Deadzone
Increase or decrease as necessary.
I find the 11 is the lowest that I can have my stick deadzone before my cross hairs and trooper start moving on their own.
Hope this helps.
spread the word - we're not the only ones having this problem.
By the way, I figure this out on my own so I didn't need to wait 72 hrs for a reply from tech support.
Oh yeah!
