Sorry, I did not notice your "cannot use subs.py or graph.py"...oops. I
would suggest just including them in your script...or at least lift the
methods out of them that you need for this and including them. I just
took all of subs.py and stuck it on the beginning of what I just sent
you, and got rid of the "subs." references (and the import subs) and it
all flew nicely....
Sorry I cannot help with the other questions...
