Thanks for the clarification, Tim.  Perhaps you folks might push out an
instruction document on the use of TNF.  Or maybe there is one and I missed
it.  Anyway, I fumbled around for half an hour before I discovered the 4X
trick.  I was contemplating sending you a note saying mine didn't work but
kicked up the zoom for another reason altogether and, whoops!, there it
was.  Perhaps just a short-but-informative popup when the user pauses the
mouse over the button for a few seconds.

I spent way too much time last night trying to break the new release and
thus far I can find nothing to complain about.

Thanks, guys.
