I tried to reproduce it, but was not successful. I saw no correlation
between the two times it happened. If it breaks again, I'll see if I
can create a conditions list, however.

My office firewall is set to always run the testing tree, so as soon
as 96 goes into beta, it will automatically upgrade (I keep a very,
very old router around in case I completely mess it up with the upgrade!
).

I really hate giving a report that says "this broke." I know you need
more information than that.
