Well, under main window file-> Pref I get:
exit
apply
save
font
and that's it.
Yes you need a newer version of xmaxima. You should be able to get it from the
cvs server:
wget http://cvs.ma.utexas.edu/cgi-bin/cvsweb.cgi/~checkout~/maxima/bin/xmaxima?rev=1.3&content-type=text/plain&cvsroot=maxima --output-document=xmaxima
I cant be sure it will be compatible with the maxima binary you have,
but it probably is. You need to set an environment variable to tell
xmaxima which maxima executable to use, ie where the root maxima
directory is eg under unix:
export MAXIMA_DIRECTORY=/home/wfs/maxima-5.6
xmaxima
Note if you are running the clisp version of maxima you would use the
same as the above but do
xmaxima -lisp clisp
this last will certainly only work with maxima 5.6.
