Probably both. Even on a reasonably fast dual processor
AMD 4300+ X2, I find TeXmacs rather slow compared to most
other apps.

Note: TeXmacs does things like build a lot of fonts when
it is first used. This can give the appearance of being
very slow at first, but this happens only once as the font
cache is built as needed.

Ok. I think one can get used to the slow speed if you learn
to like TeXmacs' features.

Can you tell me what you get if you just start tm_axiom
on the console? E.g.

  $ /usr/lib/TeXmacs/bin/tm_axiom

Reply to the weird looking prompt with an Axiom command,
e.g. 1+1

  <verbatim:<channel:prompt<latex:\red$\rightarrow$\ verbatim:1+1

you should see a coded response from Axiom like:

  2 \leqno(1)$
  }<channel:prompt<lastex:\red$\rightarrow$\ <verbatim:

This is the kind of protocol that tm_axiom normally sends to

There a few control characters embedded in this output so it
might not look exactly as I keyed above, but it should be
obvious that tm_axiom is communicating with Axiom. Hitting
control-D should end the session normally.

Let me know if this works for you or what error message
you get.

Bill Page.
