Thanks, using that now.

Odd problem, though: I've used \newshadedtheorem but now it doesn't like having figures within things:

\theoremclass{Theorem}
\theoremstyle{break}
\theoremheaderfont{\normalfont\bfseries}
\theorembodyfont{\normalfont}
\theoremsymbol{\ensuremath{\diamondsuit ...

I'm writing some guides for some people at the moment and was wondering if anyone knew how I could "color" in theorems, i.e. shade them with a different background color of any sort.
