I've had repeated crashes in the Iron Weasel mission. During the mission I aggressively go after the enemy missiles with air to air missiles from my planes. After about 10-15 minutes the game crashes. I can't attach files and trying to post them as text exceeds the 50k limit. I'll zip the files and post them here http://www.filedropper.com/logfiles_1
It may be related to alt-tabbing out of the game. That seems to be when it happens. Unfortunately, real life intrudes and forces one to do that occasionally, espicially when missions can't be saved in progress.
