pgfpages and section

Question

I'm making a Beamer presentation. I need to show some notes on a second screen, so I'm using pgfpages.

Whereas, when I put a section, it appears 2 times :/ Here, it's a minimal code with the problem. Have you any idea ?

\documentclass{beamer}
\usepackage[latin1]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[francais]{babel}

\usepackage{pgfpages}
\setbeameroption{show notes on second screen=right}



\begin{document}
\begin{frame}
\tableofcontents
\end{frame}

\begin{frame}
\section{test}
toto
\end{frame}

\end{document}

Thanks !

Never use \section inside a frame, it should always be outside.

Unrelated to the problem: the option francais for Babel is deprecated, use french instead

\documentclass{beamer}
\usepackage[latin1]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[french]{babel}

\usepackage{pgfpages}
\setbeameroption{show notes on second screen=right}

\begin{document}
\begin{frame}
\tableofcontents
\end{frame}

\section{test}
\begin{frame}
toto
\end{frame}

\end{document}
