[OzTeX] eps pictures

[Gianna Reggio]

I am using  a Macintosh with system OS 10.3
and OzTex 5.2 and I have problems with eps pictures

I generate eps using OmniGrapphle
and when I insert them in theLatex document
I can generate a dvi
print it without problems, but I cannot see it on the screen (I get a 
message
"could not create pdf from ....eps")

The same Latex source, with the same eps pictures, works well using 
TexShell

Is there any way to solve this problem?

Regards
