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.
