I also have another gui script where you move a slider around and it
changes the colormap, using
axes.images[0].set_cmap()
figure.canvas.Refresh()
in real time. It works wonderfully most of the time but occasionally
goes crazy, spouting a loop like this:

I'm pretty lost about it

Hello,
I wrote a script that loops over some files, plotting them
individually with imshow(). In between each file, the program waits
for user input and then clears/closes the current figure before making
a new one.
Roughly 5-10 files into the loop, the script dies, outputting a loop
of stuff like this until I close the figure:

Alternatively, it occasionally will tell me there are too many files
open. I have checked and all my file operations include a close(). Any
thoughts? I am using wxpython and wxAgg as my backend, with pycrust
(pyshell) on windows XP.
Thanks,
Jack
