Hi Stefan and Peter,
I logged into LON-CAPA today using your library server (polya) in the "fhwf"
domain and found that in a test course of mine in the msu domain a problem
that uses maxima (Math Response using CAS and Hints template) graded a
correct submission without error.
It would appear that either you were able to resolve the maxima problem you
were seeing with FC5, or the issue is transient.
