Okay, I realised it was switching to the itemise environment, but I
didn't know it took precedence over the latex environment.

Maybe, but I see the same problem with the following two line example
\[ x =
\begin{array}{cc} z & v \end{array} \]

Yes, I tried that, but as I understand it I need to
\usepackage{amsmath} to access the latex equation* environment. But
then I get an error about "Command \iint already defined." I tried
the solution described at
http://www.tex.ac.uk/cgi-bin/texfaq2html?label=alreadydef, but it
didn't work for me.
Anyway, never mind, these are all quite trivial points.
Thanks very much for your help,
Paul
