Hi René, looks like you're creating a document with several pages. Fine, but you need writePSfile in the first version (as EPS can be created for a single page document only).
When changing (1) to PS instead of EPS you may end up with the same problem you
observe in (2). Now it would be interesting to see how your epsfile statement
looks like.
