hi Mike,
It only prints what is between the ----, ----- . I tend to think it is
related to Tkinter.
I'm using the default GTKAgg.
I have generated over 1500 images using the simple example with no
issue. When it is in the larger app, it fails on the 2nd or 3rd request.
I'm trying
reload(matplotlib)
matplotlib.use('TkAgg')
Are there some python flags I can use when running the script to get
more verbose output? I've used -v and -d and get the cleanup list, is
that useful?
thanks
