COD4 Multiplayer PC problem?

Problem using MW3 (PC) multiplayer, really need help!?

• when i play in multiplayer i have this problem: if i start walking forward and then take my hands off the keyboard my character will continue to walk forward for several seconds. and the same thing happens when i sprint. this don't happen in campaign or spec ops. this is making it so i can't play multiplayer which kind of stinks. also, how do i change my class during a game while respawning?

• Answer:

  I think the only solution to that is to sell mw3 to your friend or someone and buy skyrim :D (kidding) I think you can't really fix that except by finding out exactly how long it does that and let go of the go key a couple seconds before you want to stop and hope that someday it get fixed
