When Alan says to run the program from a terminal window, he means,
- open terminal
- type the command to run your program - something like
> C:\Python24\python \path\to\myprogram.py

This is different from just double-clicking the program, the terminal
window will stay open.

You could also open a terminal window and just run Python, then type
or paste the pylab commands into the interpreter. I.e., run terminal,
then type
> \Python24\python
>>> from pylab import *

etc.

IIUC it is a bad idea to run a Tkinter program from IDLE, it can get a
bit confused. That may be the reason for your original error.
