Medal of Honor Glitch

Basically, my player continuously strafes left, like I’m holding the left key. It varies in intensity. So, sometimes it doesn’t do it at all, sometimes it’s very subtle, and other times it’s pretty extreme. Also, if I alt+tab to desktop for a few seconds, then tab back into the game, it fixes it for a few seconds. (and no, I don’t have sticking keys or a faulty mouse, already checked)
Just wanted to know if this is something crack related, or if it’s just a glitch in the game.
Answer #1
try and go controls and change the buttons and then press defautl again
Answer #2
Nope, that didn’t work. It’s got to be a glitch of some kind. And, I doubt there’s a work around for it. The game appears to be getting confused as to the players coordinates or something. All in all, it seems like an ok game aside from the glitches. But, I think I’ll just stick to Arma II. Every once and a while I take a break from Arma for a little arcade shooter action, but at the end of the day, arcade is for ~ censored ~.
