If I hit 'esc' during a game, it brings up the menu, and I become trapped. Hitting 'esc' again doesn't do anything. The same thing happens when I view the killboard. I have no way to get back into the game. I have literally tried pressing every single key on my keyboard, even the windows key, which just minimizes the game and opens the start menu - which I can escape out of.

Go clic on default under controls that will fix that oh and btw dont press left ctrl it unmap all your keys forgive my english

Yes, that worked perfectly. Thank you so much.
