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 [email protected] BTW: Welcome to Axiom. :-) We are actively looking for people to do Axiom development on Windows. Please drop in if you are interested.
