I presume that you are aware of the following page on the Axiom
Wiki?
http://wiki.axiom-developer.org/TeXmacs
If you installed Axiom-0.1.4 after WinTeXmacs (and therefore the
Axiom programs appear before any other in the PATH) then you should
be using a modified version of tm_axiom distributed with Axiom (see
info on above web page). In that case, setting the following options
at the top of your TeXmacs document might help:
)set output texmacs over no
)set output texmacs space yes
You can also set these are default by creating an environment
variable
TM_AXIOM='over no, space yes'
If you have problems with the Axiom verison of tm_axiom then you
can also report them here:
http://wiki.axiom-developer.org/IssueTracker
or on the Axiomm Developer list
address@hidden
BTW: Welcome to Axiom. :-) We are actively looking for people to do
Axiom development on Windows. Please drop in if you are interested.
