John,

I'd love a complete transfer of your knowledge of UI wizardry with M. :-)

Sure enough, changing EvaluationNotebook to InputNotebook worked.

In my real code, I was passing Evaluator->CurrentValue[EvaluationNotebook[],
Evaluator] to CreatePalette thinking that would silently "redirect"
everything to my inputnotebook. I clearly need to do a little more reading
in the M help in that area.

Thanks again.
