That's my fault, actually - mactex.lisp didn't get installed in 5.5,
for some reason.  I've got to fix my Maxima install.

I agree that would be good - how much work do you think that would be?

I've also got access to a Windows machine - I'll see if I can give it a
shot.

OK, then I guess I'm doing that. I'm using 20.7.1 :-)

Well, in older versions it just gave me a parenthesis mismatched error
- this would only happen once in a while.  In the new emaxima, here's
what I'm getting occasionally:

error in process filter: Invalid regexp: "Unmatched ) or \\)" [2 times]

from this input:

\maxima
diff(2*cos(x),x);
\endmaxima

It does give me output, though. In a previous cell I did this (same
session) without trouble:

\maxima
integrate(sin(x),x);
\output
(D1) 				   - COS(x)
\endmaxima
