right - problem solved.

again, not a big deal IMO. The callign code can always set the title as 
it wishes. It doesn't matter if the original page function had a 
title/breadcrumb or not. This is minor.

Huge benefit! Love the demo. The code is squeeky clean. That drupal.js 
file is stunning in its simplicity and usefulness.

PS: lets stay on topic here. Karoly's suggestion has nothing to do with 
changes to themes.
