Okay Psi, I think I've solved your large map quandry. The problem, so far as I can tell, is that you have the DIF set to 3 for that map size. When you create a game with 'large' map size and 'more' for enemy strength it generates fleets for which there aren't any discriptions (I'm guessing the DIF modifier for 'more' is +2, therefore creating DIF 5 fleets). So when the game tries to populate the map there aren't any fleets to do it with, hence the crash. If you just adjust the DIF setting for the large maps to 2 instead of 3 it works fine.

The only thing I can't figure out is how it still works on a mac.
