Tkinter Dialog Management problems:

Hello:

   Below I have included a stripped down version of the GUI I am working on.
It contains 2 dialog boxes - one main and one settings. It has the following
problems, probably all related, that I am hoping someone knows what I am
doing wrong:

1) Pressing the Settings.. Button multiple times, brings up many instances
   of the Settings Panel. I just want it to bring up one. Is there an easy
   way to do that?

2) Pressing the Done button in the Settings Panel, just erases the Done
button
   (and any other widgets in the Panel). It does not dismiss the Panel.
Pressing
   the X button does work. What callback is that? Can I make the Done button
call
   that instead? How?

3) Pressing the Done button from the Main Panel has no effect? Why not? It
used
   to work (self.quit()). Again, I would like to call whatever is called
when the
   X button (top Right corner) is pressed.

Thanks in advance:
