Ok so I tried running Marathon infinity in classic mode after I just downloaded it from bungie.com. So I downloaded it and it automaticly unziped the sit file with expander onto my desktop. I opened up the folder and clicked the icon for Marathon Infinity 1.5. So than classic mode started up. After classic mode was done starting, I just got a blank black screen that flashed a couple of times and than, the top 3rd of the screen turned white and had a few pixely, ill-legible icons but i had no mouse. after that nothing I pressed would do anything for the game. So I force quit. Now I get flashes on my screen every couple of minutes from classic mode. Does anyone know what problem Im having with this? Is it my iBook, the game, or is it classic mode? Help would really be appreciated. Thanks!!!
