[Image-SIG] Tkinter / Pmw shutdown crash - please help

[Joel Gould]

I have attached a very simple Tkinter program.  When I run this on my
Windows 98 SE machine, a crash occurs when the program exits.  Without the
MainDialog class it works OK.  Without the Pmw initialization call it works
OK.  But as written it will crash around 75% of the time.

(1) run the program
(2) press the Test Button
(3) click Cancel in the file open dialog (you do not need to select a file)
(4) click the close button in the upper right corner
-->  Boom

Does anyone else see this behavior using Python 2.0, Py20 from Pythonware
and Pmw 0.8.4 on Windows 98?

Thanks,

Joel Gould

root = Pmw.initialise()
dialog = MainDialog(root)
root.mainloop()
