I mean a program that is half-widget and half
something else. You haven't indicated whether
your program runs without the XManager call,
but I suspect you are in the nether world
between a widget event loop (whatever the hell
that means) and the interpreter.

(And where are all you guys (Pavel!) who are
suppose to know something about this? I'm
on my tippy toes here and I still feel like
I'm drowning.)

I think this ... whatever ... is what is causing
your problem. I can assure you that if this
program was a proper widget program (without
any RETALLs, for sure) it would run as a run-time
program.

How does dialog_message return to you the
window they want to draw in?

If this works, what is the problem?

Cursor has nothing whatsoever to do with event handling,
at least not in any widget sense. I think, in fact, that
this must be handled by the command interpreter, which is
not available in run-time programs.

To know for sure, I need to see your program (which I
really don't want to do), or I need to build an example
program (which I really, really don't want to do). :-)

Are you talking about Logan? Oh ... you!

No, not at all. The alternative is puzzling over a program
I'm trying to write that I think I already wrote as an example
program. The problem is, I can't seem to figure out how it works,
and it *is* a widget program! :-)

Cheers,

David
