I wouldn't worry about it Bill, since I had trouble duplicating the effect
after I'd moved the frame divider initially, so I suspect it's highly
sensitive to exact pixel position and possibly other things like screen
resolution, which is 1024x768 on this old desktop.
If we can't easily reproduce it and we've never experienced it before, I
don't think that it's likely to crop up too often, especially since it's
partially dependent on a very deep thread, possibly with some similarity to
the flow of that specific example.
Notably your's was the last post in that specific thread, so I guess that
means for proper viewing Engel and I can't allow you to have the last word...
hehe.
