You are right, I should have dropped this into the Tkinter mail list. 
Thanks for the info, but I think I'd like to stick to Tkinter for now. I 
do have a way out of my dilemma. I'm trying to draw something like a 
compass, and I don't necessarily need the lines emenating from the 
center to the edge of a circle. I can just intersect the circle with 
maybe a 10-20 pixel line. Out of curosity, I will re-post over in Tk-ville.
