Niels,
Looking at the HTML source, I see
<div ex:role="coder" ex:coderClass="Color"
id="party-colors">
<span ex:color="red">Republican</span>
<span ex:color="blue">Democratic</span><p/>
<span ex:case="others" ex:color="#aaa">Other
parties</span>
<span ex:case="mixed" ex:color="#eee">Many
parties</span>
<span ex:case="missing" ex:color="#444">No party</span>
</div>
I think the <p/> is causing problem. Could you remove it and see if that
helps?
David
