Has no one answered Mr. Faulconer's question? My impression is
that it's MUCH easier than he's making it, but I'm not in a po-
sition to address it any time soon. I sure don't want him
thinking that we're unresponsive or that Tkinter is difficult,
both of which I know to be false, with occasional exceptions.
'Anyone comfortable with PMW have time for this?
