I saw a post from Dec. 2008 talking about using ntheorem with beamer, but I cannot get it to work at all. Just loading the package returns an error for me. Here is a minimal example:
(/usr/local/texlive/2008/texmf-dist/tex/latex/beamer/beamerbaseauxtemplates.sty
\documentclass{beamer}
\usepackage[standard,amsmath,thref,hyperref]{ntheorem}
\begin{document}
\begin{frame}
\begin{example}
hello
\end{example}
\end{frame}
\end{document}
I get the following error:
Package ntheorem Error: Theorem style plain already defined.
I have the following versions of beamer version 3.07 and ntheorem version 1.25
Thanks in advance for any suggestions.
