The idea that comes immediately to mind for me is to write
an object that "checks out" top-level base widgets. But
objects are so incredibly difficult to write that you
practically have to be a genus to write one. :-)

I think one or the other of us is confused about what "modal"
means. I am certain that any widget program "triggered"
by a button from a modal widget is--almost by definition--
guaranteed NOT to generate events itself. At least I've 
never gotten it to work.



P.S. I was reading this is my Psychology 101 text: "Sometimes,
with particularly recalcitrant children, it is necessary to
espouse exactly the *opposite* tack from the one you wish them
to take. This is known as "reverse psychology"."
