The problem wasn't a lack of memory. While it was displaying the beginning turn messages, such as an upcoming UP Council Vote or such, the Control Panel would scroll through a computer player's fleets and planets. If I didn't hit the Done button fast enough, it would crash to the desktop. I think it might have something to do with planets defecting, since it only began late in the game, when planets were starting to defect regularly and there were a lot of newly homeless fleets around. In fact, during the 10 week wait to win the Influence Victory, it was displaying every turn. Personally I think it is a problem with V1.2, and I said as much when I wrote about in the Bugs Forum, but I haven't got any useful replies. Thanks for trying to help, though.
