tkFileDialog closes main application

[mdmdmd]

Thanks for the reply.

I used your modified code to test.  I ran the code on Windows Python 2.4 
tcl/tk 8.4.  When I opened the ui I:
1) click browse button
2) file dialog opens and I double click the file.  When I do this, the 
selected file path is entered in Entry field. I don't need to close 
dialog, it closes automatically.
3) click browse button again
4) double click file
5) repeat

sometimes it only takes one time to kill root, sometimes a few more. 
After I killed root with the double clicks I then tried with a click 
browse - select file - click open button very slowly making sure I 
didn't double click and the same thing happened - root was destroyed.

BTW, with your modified code, the "Closed by the WM" was not displayed 
to console.

Hmmm?  I think this must just be peculiar to Windows.  Can any other 
windows users test to see if they can reproduce?

thanks again for your response.
