GTK 2.2.4 (Can't remember where I got it. There's been a few of these 
floating around.) Pygtk 2.0.0 from the link in matplotlib site.

Somehow my GTK runtime don't have the png, jpeg etc images libraries and 
I got them from the gnuwin32 sf site.

I followed the link in the matplotlib site and installed gtk 2.2.4.1 
from the sf site and the problem goes away. This version has all the 
images libraries with them. I must bookmark it!

Another question: I've set the environmental variable AFMPATH in the 
registry via the control panel but matplotlib complains that the .afm 
files are not there.

This is a W2K system.

Thanks very much,
