Keyboard crashes

Hello,

I encounter the problem that sometimes when im closing a window/menu ingame and i am pressing another key simultaneously, the key is stuck. Already happened to WASD keys Tab and Alt - Ctrl..

Can only be Fixed by re-plugging the keyboard...

Anyone ever faced this?

Keyboard = Microsoft Wired 600 (new drivers already installed) Win7 64-Bit

Thank you & Goodbye

Oh, i forgot the system Information...

By the way, i figured out that it has nothing to do with closing menu windows but with pressing keys simultaneously like running, opening the map and looking around with the mouse, all at the same time.
And it happens only in this Game.
