right side of slide is "cut"

Hello everybody,

I'm currently preparing a presentation for a student project of mine - for the
first time using prosper. It seems to be the tool I need, but I have the
following problem and no idea how to solve it:

The rightmost part of the slide (e.g. including the slide number) simply doesn't
appear when I view the document in AcrReader. It seems that about 1cm is "cut
off" on the right part.

Here is my, very simple source:
-------------------------------------------------------
\NeedsTeXFormat{LaTeX2e}
\documentclass[pdf,a4paper,frames,slideColor,colorBG,accumulate,nototal]{prosper}

\title{Incremental Maintenance~\ \\ of Materialized Views~\ \\
   in QFCSuite}
\author{Mirko Steinle}
\institution{Swiss Federal Institute of Technology of
Lausanne\\QualiFlowCheck}

\begin{document}
\maketitle
\end{document}

------------- that's all -----------------

I'm working with WinEdt, and I'm executing the following command sequence to
create the pdf file:
latex -> dvips -> ps2pdf.

I didn't find any hint in the archives...

Thanks for your attention - Any advice would help me a great deal.

Thank you very much in advance.

Mirko
