I've started playing MM8 and everything appears to work fine most of the time. But every now and then the game crashes to desktop due to a mm8.exe error. There doesn't seem to be any regularity in this, and it doesn't ever happen in the same spot twice. I've tried to cope with it by quicksaving often, but it's starting to get frustrating.
I'm playing on Windows XP Professional with Greyface's latest patch installed and drivers updated. I also had no problems of this sort with MM6 and 7.
