Thank you all for replying. Sorry for the delay. (I've had a proposal
due today and have been doing nothing but that.)

Yes, it is still a mystery. It doesn't crash every time. But sometime,
and this happens _all_ of our machines it starts crashing. It does it
consistently, for all sheet names, under all circumstances - until it
magically stops. I think a reboot helps. Next time it happens I'll
capture the stack and post it (I have no idea what it means...)

Thanks again.
