I just downloaded AA 'cause I want to play some realistic simulation of the army. Everything has been good, I installed it perfectly but when I get on to the training, a problem appeared. Everytime when I move, either forward or backward, right or left, there's a tendency of the computer to keep moving even when I remove my finger off the keyboard. I can only reverse this by double tapping the key. This is really frustrating especially for the obstacle training, and I know I can't play anywhere if this problem is not deal with. I'm not saying this is a bug 'cause it has happened to other games I've downloaded as well, so I'm asking has anyone else experienced this problem and how to fix it? Any suggestion?

Thanks!
