I think I want a "dumb" form because I might have several different
processes in different parts of my program that are long running and I want
to the progress form to be able to be used by any of them without changing
it's underlying code. That's why I was shifting most of the processing out
of the event handler for the popup form. My goal was to make it generic in
the sense that any long running function block could pop it up and pass
progress messages to it.
