Default Maxima's plotting system



Hi!
I've faced with the following problem by using 
standart Maxima plotting applet (Schelter's 
2d-3d). It plots the graphs, it's also possible to 
rotate and move the graphs, but problems occur 
when I try to make some actions using menu (like 
save to ps) - it simply doesn't react, I press 
these buttons and no reaction. Yes, I've found 
that's possible to change it to 'gnuplot'. But 
unfortunately I haven't found any opportunity to 
save graphic data to .ps (or something readable) 
in gnuplot.
Am I alone with such problem or have smb. esle the 
similar one?

Sincerely,
Yuriy
