texmacs+maxima



Can someone tell me how to run maxima under TeXmacs installed on a
windows-machine?

My TeXmacs works fine (under cygwin), and I can for instance run a Gnuplot
session by choosing
Insert
   Session
      Gnuplot

As far as I know Maxima should be activated in a similar way, but how can
I add Maxima to the list of sessions?
I've tried
Document
   Add package
      Session
         maxima
(Yes, maxima is on the list here!) but nothing seems to happen (TeXmacs
replies with 'generic maxima text roman 10').
Should I download or install something? If yes, what and how?

Yours,
Poul Riis
