I think that what you describe is OS-dependent and perhaps Mac-specific.

In Windows (XP), at least as far as I can see, there is no such File 
menu item "PrintSelectionAs".  There's a "Print Selection" item which 
gives one the choice of printing to a specific printer (i.e., printer 

In Windows, there's also a "Save Selection As" item, and that offers 
both EPS and PDF -- but unfortunately no PS.  And the result of saving 
as EPS has exactly the same bug as Export to EPS: the outside surface is 
almost completely opaque, so that the arrows inside are obscured.

As I said in another post to this thread, my workaround was to export to 
PDF instead of EPS.  The down-side of that was that I had to use 
pdflatex on my LaTeX document, which goes directly from .tex source 
(with an \includegraphics for the .pdf graphic) to pdf -- instead of my 
usual workflow from .tex source (with \includegraphics for .eps graphic) 
to .dvi viewed in a previewer, and only then via .ps to .pdf final 
document.  Since pdflatex is generally much slower to process and view 
than latex to dvi, the workaround is undesirable.
