Who's on First, IDLE or pythonWin? Dialog Problem?

[W. eWatson]

My program in IDLE bombed with:
==============
Exception in Tkinter callback
Traceback (most recent call last):
   File "C:\Python25\lib\lib-tk\Tkinter.py", line 1403, in __call__
     return self.func(*args)
   File 
"C:\Sandia_Meteors\New_Sentinel_Development\Sentuser_Utilities_Related\sentuser\sentuserNC25-Dev4.py", 
line 552, in OperationalSettings
     dialog = OperationalSettingsDialog( self.master, set_loc_dict )
   File 
"C:\Sandia_Meteors\New_Sentinel_Development\Sentuser_Utilities_Related\sentuser\sentuserNC25-Dev4.py", 
line 81, in __init__
     tkSimpleDialog.Dialog.__init__(self, parent)
   File "C:\Python25\lib\lib-tk\tkSimpleDialog.py", line 69, in __init__
     self.wait_visibility() # window needs to be visible for the grab
   File "C:\Python25\lib\lib-tk\Tkinter.py", line 415, in wait_visibility
     self.tk.call('tkwait', 'visibility', window._w)
TclError: window ".34672232" was deleted before its visibility changed
===============
It runs fine in pythonWin performing the same entry operation. Open a menu, 
  select an item to open a dialog, select a select button in the dialog, 
press OK to leave the dialog. Boom, as above.

(This does not mean pythonWin doesn't have problems of its own. ) If I just 
execute the code (double click on the py file, the console shows no 
problems. IDLE is unhappy.

Another side to this is that I use WinMerge to find differences between my 
last saved copy and the current copy. I found the current copy had two lines 
where a abc.get() was changed to abc.get. This was undoubtedly from briefly 
using the pyWin editor, when I mis-hit some keys. Yet pyWin had no trouble 
executing the program. My guess is that while briefly editing there, I hit 
some odd combination of keys that produced, perhaps, an invisible character 
that pyWin ignores.

Not the 34672232 window is a dialog that I closed by pressing OK. I would 
again guess, that, if there is a problem, it occurs in the code that 
destroys the dialog.
