Thanks, but that did not work.  The only thing that seems to work is
to put {none} for the caption.  However, that means I'm not going to
have captions in the manuscript version either.
well, we can misuse the number= key .....

(I'll add that to the core, but only if you wikify it)
and what is the difference in the output compared with my solution,
the following works for me and I have no caption in the second figure.
