I'm trying to create a navigation panel for a heavily graphic based site, which requires a graphic for the "scrollknob". I have been able to fix the height of the scrollknob div visually, but the javascript still acts as if the rest of the bar is there, meaning that the scrollknob sticks halfway down the scrollbar.

http://danbeckett.co.uk/mooscroller has a working example (although for the moment I am letting the graphics tile via repeat-y so I can see if I'm making a difference in the javascript).

The relevant CSS file is located at
http://danbeckett.co.uk/css/mooScroller.css

and the javascript:
http://danbeckett.co.uk/js/mooScroller.js

Any help at all that could be offered would be appreciated so much, even down to pointing out what section of code needs editing.

Thanks - Dan
