Help : pdf figure is black !

[Maurice Diamantini <diam@ensta.fr>]

Bonjour à tous,

I'm trying to switch from Latex + pstrick to latex3 and Metapost 
(alias context :-)

For now, I'm trying to reproduice a Latex + Seminar + pstricks slides.

Before to switch to Metapost, I'd like to include the pstricks figure 
as pdf external file (from eps file)
The figure is OK and I can see it with xpdf or acroreqad.

But when I use it in ConText, the background is all black.
I've been unable to play whith the  various option :

    2
    \externalfigure
        [01-problematique.pst.pdf]
        [width=0.4\textwidth,
         % bfactor=0.9,
         % raster=0.9,
         background=screen,
         % background=color,
         backgroundscreen=1.0,
         backgroundcolor=yellow,
        ]
    3

Any idea ?

P.S.
I think that the "Context" name is a bad choice, because it's
difficult to find on the web (to much pages are found)
It would be better to name it "ConTeX" !

Maurice.
