I have maxima 5.5 beta 3 with a mandrake 7.1. When i launch xmaxima, i
can enter and evaluate the expressions, but when i click on the items
of any menu, it will do nothing.
I have never seen this. It would appear to be a problem with wish
(ie tcl/tk), on your machine or with your window manager. Try
restarting the window manager -- at least this is what I do with fvwm
when for some reason I can't get netscape or other applications to take
the focus.
You might also check the wish demos: run
/usr/lib/tk8.3/demos/widget
or whatever version tk you have.
