This may be a system specific error -- it's certainly wierd enough! -- but when Sins crashes to produce the minidump dialogue box, it doesn't actually crash first. It only crashes after I hit OK on the dialogue box... it just sits there, frozen, and I can't figure out whats wrong until I alt-tab out to see there's a minidump going on.
Since I can't play for more than 2 minutes without a minidump, this is a problem...
