Thanks for the explanation, Jonathan.  And yes, I did search for it and I
got hundreds of results.  There is no way for someone like me to go through
all that and figure out if it's a duplicate.  So, as I said, I've reported
it.  Don has already responded to the bug, and it seems that it's Linux
related as he can't reproduce it on Windows.
