I'm running windows 7 64 bit on a HP Pavilion dv7 lap top. When I am playing call of duty modern warfare 2 the tilde ~ key will not function in game to bring up the console. This seems to be an on going problem with windows vista and windows 7. Can someone please tell me how to get the tilde key to work while in game? I have tried disabling the infared thing in device manager but that doesn't help. Any suggestions?
