[Edu-sig] graphics module

[John Zelle]

Brian,

I had to do some tweaking of this code to make it work a little better 
with Python 2.3 and IDLE 1.0 on Windows, and the result is this annoying 
behavior you mention with your slightly older setup. When I have some 
time, I need to really sort through the issues here rather than applying 
band-aids. In any case, I think there is a simple fix for your 
situation. Take a look in the graphics.py file and locate the GraphWin 
class (it's the first one).  The close method looks like this:

def close(self):
    """Close the window"""
    self.master.destroy()
    self.quit()
     _root.update()

Simply comment out the second line, "self.quit()",  (i.e. put a pound 
sign in front of it). I think this will fix your problem. Please give it 
a try and let me know if it works; I don't have a setup for testing your 
version here.
