Melee/Greebo's CraterMA: when closing A47 in order to shoot the ack, the game stopped responding. Went back and the auto save had taken me to the other side of the field. Turned back and when I was close enough to locate an ack, stopped responding again. Ctrl-Alt-Del->TaskManager enabled using the mouse and helped getting out the situation. The error details are as following, I suppose it doesn't really matter that the titles are in Finnish:
