A user of my tabber script discovered that when his tab headings had an ampersand character like this:
<h2>Me & My Shadow</h2>
Then the tab control displayed “&” instead of a single ampersand character.
and replace with the following:
DOM_a.innerHTML = t.headingText;
I’ll think about this some more and if I can’t find any bad side effects I’ll add to the tabber code.
