While building a basic app using the winapi with Python 2.7 (I'm on Windows 8.1), I tried to add a small Tkinter gui to the program. The problem is, whenever I close the app window, Python crashes completely (getting crash messages basically).

I have found reports of this issue in several places, but couldn't find a fix or solution. Here are some sources:

http://sourceforge.net/p/pywin32/bugs/443/#8bde

http://www.gossamer-threads.com/lists/python/python/134956 (this one is from 2002!)

It can be reproduced with as much as these 4 lines:

from Tkinter import Tk
import win32uiroot = Tk()
root.mainloop()

And closing the window after running it. Does anyone know of a solution for this? Any recommendations for a workaround maybe?

A workaround is to invoke the Tkinter-win32UI app with pythonw. Python doesn't crash.

Tested with Python 3.6.3 on Win 10.
