Thanks. You're probably right. I'm sort of stuck with this (2.4.4). The 
supplier of the s/w I am working on distributed it under 2.4. There are a 
number of people who are using the program, and aren't python savvy. The 
supplier has moved to 2.5. I'm trying to provide a program that will run for 
them, and probably 2.5. I find it odd though that this simple program on 
the matplotlab never got checked by someone. I suppose it's possible.

I'm giving this one more try (a new post shortly). If not, I'm dragging 
everyone up to 2.5.
