Tkinter Window refresh

[Daley, Mark W]

I am reposting this with the hopes that the answer lies with someone out
there.  I searched all the documentation and books I have, to no avail.

> I have no idea how to do this.  I want to allow a user to manipulate a GUI
(e.g., shrink it to the toolbar) while it is performing an operation in
another thread.  I am told what I want to do is
> invalidate the GUI window every time an event occurs within it, whether it
is a mouse click or the removal of a window that overlays it.  Does anyone
know how to do this?  I am looking in the os
> module, but no luck yet.
