Game menu locks out keyboard? Please help

Im having trouble running the game menu while I’m in a game. If I hit f1 the menu comes up. I can scroll up and down and navigate thru with x/z. I can’t change any of the game controls tho. When I hit x nothing happens. If I change the bind mode to keyboard then I can changet the inputs. BUT, only for the first 5 keys. No matter which 5. After 5 when I hit x to get into the input (a,b,c,up,down,left,right), the little window comes to change it but only enter will get me out of it. Not even esc. Any suggestions?
