[pdftex] href

[tino_schreiber at web.de]

Hi,
I use MiKTeX pdfTeX 1.10a.
To open a pdf-file (test.pdf) in a pdf-file (myfile.pdf) I write in myfile.tex:

\documentclass{scrartcl}
\usepackage{hyperref}
\begin{document}
...
\href{test.pdf}{here!}
...
\end{document}

(test.pdf, myfile.pdf and myfile.tex are in the same folder.)
After the compiling I get myfile.pdf. OK.
In myfile.pdf I open test.pdf. OK.
Now I close test.pdf and myfile.pdf is closed too.
What can I do to get that myfile.pdf is not closed too?
or
What can I do to get that test.pdf is opened in addition to myfile.pdf?
Thanks,
Tino Schreiber
