I have a problem with my key board keys sticking on my old key board, when I switch to my browser while in MW2 on my 2nd monitor. the keys are 9999 ===== . So to get out of that problem I have to close down the game and restart the computer and it is gone. I thought it was the key board as it is a few years old. So I bought a new one and started using it this morning and the same thing happens. Any ideas how I can fix this?
