I have a new 2.6 MBP with Leopard and I decided to try the chess game. It is great until it locks up on me. It gets stuck on "blacks move" and it seems to happen every time I am chasing the King. Sometimes I can save the game, close the program, and open it again then it works. Sometimes it just doesnt have an effect and stays frozen. Is this happening to other people? I found a similar issue by searching on google, but no help.
