The traditional fix for this issue, in this instance - is not working for me. The vertical scroll bar persists. See below:
It looks like the fiddle successfully works because the scrollbar of the inner
#scroller div is being hidden by the outer
#wrapper div. Notice that
#scroller is 20px wider than
#wrapper. Try setting widths for your divs, making the inner div wider than the outer, and see if that gives you the result you're looking for.
