I have a user at our site who is trying to reference an equation as
part of a figure caption. The equation is tagged normally, but when it
is referred to in the caption, LaTeX gives an error message saying
that there's a missing } in the \caption, along with a flurry of
messages following.

Any of you out there who have written theses or papers probably has
used a reference in a figure caption, and might have seen this before.

Below is a little sample file that does'nt work on either our Sparc,
or Vax version of LaTeX.

\documentstyle[12pt]{article}

\begin{document}

\section{The Extraction Technique}{\ }
\begin{equation}
id=id
\label{idovergm}
\end{equation}

\begin{figure}[h]
\caption{Equation~\ref{idovergm}  }
\label{idgmvsvgvth}
\end{figure}


\end{document}

It's really simple, and should work. But it does'nt.

Any help is greatly appreciated.

Thanks Alot,
Paul Orphanos
