New submission from Eugene K.:

I've encountered this while trying to write a program that allowed the user to 
edit button labels, by creating an Entry widget on top of the  Button, and then 
hiding the Button. 

Sample code:

According to feedback from stackoverflow, it works as intended on MacOS and 
Debian. It does not work in Windows (I've tried Windows 7, 8, and Server 2012 
R2, with Python versions 2.7.5 to 2.7.9.)

The problem is that the button does not want to stay hidden. E.g. I create an 
Entry widget and it initially appears on top of the Button. Then, if I click 
inside the entry box, it briefly disappears (for a second or two), showing the 
button again, and then reappears. If I hit 'tab' and move focus out of the 
Entry, it disappears completely (exposing the button again) and only reappears 
when I click back into the entry/button area.
