[Tkinter-discuss] tkFileDialog: shuts down root window

Ahha!  I know how to reproduce this!  I was starting to think it was the
Eclipse IDE but I did a reboot and ran from the windows console to make sure
it wasn't

to repeat:
1) Right after reboot, I opened a window console, did a cd to my python
directory and entered "python <mytestcodemodulename>.py" to open the ui
2) click the browse button 
- file browser opens with my list of .csv files
4) here is the trick - DOUBLE click the file you want in the list.  
- with the double click you don't need to click the Open button, the double
clicked file is entered in Entry field and tkfiledialog window closes
5) click the Browse button in the UI again and here is where I get some
different behaviors.  Some times after clicking the browse button the second
time, I can wait, (for me it took about 15 seconds), and then the root
window is destroyed.  Other times, the root window is destroyed immediately,
other times I need to do the browse, double click, browse, double click
three or four times.  But seems that I can consistently repeat this with at
max four of these browse, double click cycles.    

It seems that all I have to do is have one double click in the tkfiledialog
to kill my whole app.  Can anyone else reproduce this? 

Thanks again.
