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.
