hi everyone,
i want to use PPCHTEX. when i process my .tex-file with texexec i get 
the message:
    .....
    specials : fdf loaded
    )
    specials : fdf,tpd loaded
    \openout6 = `chemie-mpgraph.mp'.
    Randomizer initialized to 1275417501. [MP to PDF] 
(./chemie-mpgraph.4000))
    *

and the program stops and waits for a command. when i type \end  it 
continues. this happens again and then i have my target file.
what wants the system tell me? why does it stop?. it's irksome, to type 
in a command for nothing. when i process with latex everything is ok.
