Yes, ever since I upgraded to a new version of the Python Image Library (last week), MathAction seems to occassionally go into a mode where it cannot render LaTeX images properly. I do not yet know the cause however with a little tweaking (like restarting the web server and deleteing the improperly generated images), I can manage to get it to work for a while. (I have made such corrections to this page.)

I am investigating the problem now. Please be patient. Thanks.
