I am particularly pleased to hear that the new interface is working on
windows. The only testing I did there was months ago, when the interface
was still in the concept-only stage.

It would be nice if we could understand this problem.

As I told Valery, the bug isn't in maxima or gnuplot -- it is in me. I
mis-transcribed the command on the web page. It should have been
plot3d(cos(-x^2+y^3/4),[x,-4,4],[y,-4,4],[gnuplot_preamble,"set view map\
;unset surface"],[gnuplot_pm3d,true],[grid,150,150]);
The [gnuplot_pm3d,true] option was left out. I have now updated the web
page with the correct command.
Thank you very much for testing the new code.
