[IronPython] WPF / ipy minimize weirdness?

Thanks for the note!
I was thinking more about this last night - the app is a legacy thing I've
taken over, where the modal selection dialog is quite a heavy-weight entity
- it captures about the same amount of real estate as the underlying
application itself, with a dozen or more controls on it, and the user may be
fooling around with it for 4 or 5 minutes at a stretch. We've concluded that
it should really just present as a separate page on the app, rather than as
a modal dialog, and probably next release we'll be moving toward that; it
solves a stack of other interesting problems as well.
For the time being, we are trying to get to a point where someone may have
not finished messing with the selection dialog, and wants to just minimize
the whole thing (selection and main app window) in order to move to another
app. The 'other app' may be another copy of this one, just running on a
different data store, thus the need to get rid of (minimize completely) the
1st copy to avoid confusion! Obviously, when we move to a single window
design this problem goes away; right now just trying to get the two windows
in the app (if the selection dialog is active) to act "in unison".
In answer to your question, without any event handlers in place, I can
minimize the selection dialog using the standard Windows "_" control, which
leaves the main app window in view, but totally disabled - minimize, exit,
etc. are disabled along with any of the app's controls. Taskbar still had
two icons, one for the dialog and one for the main app, and I could restore
the dialog and continue.
When I added in an event handler, both the selection and main app windows
disappeared, with the modal dialog apparently completely gone (no taskbar
icon any more) and the underlying app still waiting for it, so it's taksbar
icon was completely disabled, unable to restore, cancel, anything.
Hope to get this to work in some fashion, but as I said, I'm going to be
turning this into a separate page for a single app at some point so I may
find some interim not-quite-what-they-want solution if this turns out to be
too much effort to get going.
