App Store version constantly Crashes

[jens]

Wait, you are saying that you don't actually reboot the computer? Rather you put it to sleep/hibernate and then you bring it backup and sometimes you can continue playing and sometimes the game crashes so you are returned to the desktop?

Can you try and go into System Preferences, Energy Saver and turn off all the sleep/off settings and then try playing the game? I'm just getting a weird hunch that the game might hang as the computer tries to go to sleep, possibly because it does not register activity in fullscreen properly.

Unfortunately the hpl.log files does not help anything, there is no useful info in them. So we need to try and get some system log with information.
