I have experienced an annoying behaviour of LaTeX.  When I use a reference
inside math mode
the TeX program hungs up without any error message.  I have reproduced the
problem in the small document below.
This happens when using  \usepackage[spanish]{babel} and after using \chapter.

I am using MiKTeX 2.2

Is this a bug ?
It is not a problem, but if you do not know the reason why the program
hungs up you cal lose quite a lot of time.

======================
\documentclass{book}
\usepackage[spanish]{babel}
\begin{document}
\chapter{Chapter}
$$\label{label1} a=b+c$$
Using the reference $(\ref{label1})$

\end{document}
