As for the error logging, nothing stands out, the second theory was actually more related to the crashes that happen when you're repeating actions, or doing things quickly. Othello is a good one to crash if you try quickly flipping between the screens, if you take your time it's fine.
When you say "crash", you mean it locks up in MESS, but doesn't otherwise cause MESS to die, correct? Just so I know what to look for.
