Sometimes i go in and out of the game using ctrl+alt+del then using task manager to get out of the game(this automaticaly minimize the game) to see maps on chrome.....once i'm done i click on the ico of the game in my task bar and go back to the game full screen.

I always assign numbers on my keyboard(above Q) to weapons, binoculars, and the likes...

Thing is that sometimes, i can't get anything in my hand using numericals keys,,,,everything else is fine...tab, f key, w-a-s-d, sapce bar bit i can't get anyting assign to a number....i have te restart the game to get these keys back
