I have an annoying glitch which means that I'm never stood still, when I'm not pressing anything my character creeps forward slowly, Iv'e tried disconecting the controller and it still does it so I think its to do with the game, not the controller. This makes the game difficult as I'm trying to complete 'come fly with me' and I'm looking for teh shipment od stealthboys, I know where they are but cant get to them because I need to jump from box to box, and as I'm always walking I just fall off. Also, when I'm hiding in some cover it means that after a few seconds Iv'e crawled out into the open! I keep falling off cliffs and aiming is also difficult. Any ideas what to do?

Cheers
