I have just implemented this jquery plugin nanoScroller.
My work to date: http://jsfiddle.net/tebrown/uXV7c/11/
The trouble i am having at the moment is creating more than one scroll bar within 3 tabs.
The first tabs works fine, although when you go to the next tab, it doesn't show. Ideally i would like this to work within multiple tabs.
Any help would be much appreciated.
Cheers
