[Pythonmac-SIG] Problems with Tkinter

[DrBHorow@aol.com]

I'm a physician and love to program in my spare time. I've had alot of 
experience programming in Tcl/Tk and just started learning Python, 
particularly to explore Tkinter. 

I'm trying a simple script like this:

from Tkinter import *
root = Tk()
button = Button(root, text = "Test")
button.pack()
root.mainloop()

Everything works ok on the Tk end of things. The toplevel window appears with 
a button and accepts clicks. The problem I'm having is that as soon as Python 
interprets mainloop(),  Tk takes over the menubar and all event handling. I 
can't reliably interrupt mainloop. Even when I do interrupt it (sometimes by 
typing), the original menubar in the Python interpreter is not restored. 
Windows do not refresh properly. I usually have to quit Python to the Finder 
(by hitting command-option-shift-esc).

I'm running a G3 powerbook/OS 8.1 or 8.6, Tcl/Tk v8.0, Python v1.5.2.

Any help would be much appreciated.
