I'm playing on a Tungsten T2 with over 9mb free memory. After the first crash (after starting a new game), the program reverted to the previous game (with dead villagers scattered all over the place). After that I found that if I'd pause the game periodically it would at least continue the current game when it crashed again. The biggest problem is that when I reboot and resume the game, I lose babies but GAIN lots of tech points. It may be my imagination, but I believe it's been crashing less with the tutorial turned on. The most consistent crash is when I try to open any other program. Hope this is fixed soon.
