I use MixTeX 2.9 with Windows. I have a problem when compiling with the Prosper document class. My code begins as follows:
\documentclass[pdf,distiller]{prosper}
\usepackage{amsmath}
\usepackage{Sweave}
\usepackage{xkeyval}
\title{Multiple Response Optimization}
\subtitle{}
\author{St\'ephane Laurent}
\begin{document}
...
I compile with 1) latex, 2) dvips, and 3) ps2pdf. In the pdf file the slide is not well centered:

I have tried several options with dvips but nothing changes.
prosperclass and its companion patching packageHA-prosperare no longer maintained, as far as I know; the authors recommend to usepowerdotinstead. – Gonzalo Medina Sep 12 '12 at 2:32
