What were you trying to do?
	destroy teh last windown of a Mosaic running out of the

Yo, got any documentation, or other info?

I have the crashdump too.


Hmmm, I think the copy of Mosaic may have changed out from under me
while it was running, which might explain why it lost, but not why the
machine panicked.
