I just got JK Friday. When I am playing the game and I hit esacape to go to the menu, my game closes down when I try to reenter the game by hitting escape of clicking return to game. Does anyone know how to fix this.
I think that I found what the problem was. When I come to a place where there are transparent graphics (water, windows, etc.) my machine would slow down, so I turned on the backbuffer (I think that's it) under the display section in the menu. The graphic performace increased, but that's when my game started to messing up. I reinstalled the game and I'm playing with the backbuffer off and everything works fine now.
