Keyboard stops working

Not sure if anyone else is having this problem, but my keyboard randomly stops working. I think its happening when I alt + tab out of the game to view something online. I come back and can't type anything. The mouse still works in game and the keyboard still works in other programs on my computer. Exiting out of the game and trying to load it again does not solve the problem either cause when I bring up the launcher the keyboard wont work there either. It will fix itself if I reboot though. Think I had this issue once before the patch as well so not sure if its my keyboard or something to do with the game.

I am running windows 7 and use a logitech g19.
