I have been struggling with this for a couple of hours: Including the package [`lscape`](http://www.ctan.org/pkg/lscape) immediately rotates the whole document. I have no clue why it happens. The document is very simple:

```
\documentclass[aps,pre,preprint,superscriptaddress]{revtex4-1}
\usepackage{lscape} 

\begin{document}
\title{}

\maketitle

\section{section 1}
A paragraph
\end{document}

```

Even with a `\begin{landscape}` environment the whole document is still changed. 

Thank you ahead for any comments.
