When attempting to use the debugger with the simplest of tk programs, a couple
of problems are observed:

1. An exception is reported when the breakpoint is set.

2. When stepping thro portions of tkinter, the coordination between the source
window and the debugger are lost after about line 1000.

Below is the source script and the exception report.

Are there known limitations when using the debugger with tkinter stuff?
This script works fine without the debugger.

I would appreciate advise.

''' First test script.


from Tkinter import *
def test():
root = Tk()

w = Label(root, text="Hello, world!")
w.pack() <<<=== Breakpoint here!
