My students have been using openmath for the plots, without
problem. None of them has run into the window-manager problem you
have, so the can access the menu and use menu options to save the file
as postscript.

It does not have great quality, but if you tell your students to
always use "mark" to select a plot region, I think the output is
acceptable. For book quality results I use my own postcript macros
which I hope I can incorporate some day in openmath.
(see example.ps attached; the actual plot is done in the last 23 lines
after %%Page: 1 1)

One thing I always have to remind my students is that if they work in
xmaxima (the only option for those using Windows), they must end every
plot2d or openmath_curves command with ";" and not with "$"; otherwise
openmath will get stuck.
