Found another layout problem.
not sure if its mod related or the vb navbar but it seems mods like BF - Easypages and a Photopost mod makes a mess of the navbar ?
examples :
BF EasyPages -
http://www.pygmychameleon.co.uk/pages.php?pageid=1
PhotoPost -
http://www.pygmychameleon.co.uk/gallery/
all other pages are fine with the default style navbars. -
