ScrollTo jumps to 'top' element when using scrollbar in Firefox

ScrollTo jumps to 'top' element when using scrollbar in Firefox

When using the side scrollbar in Firefox (scrollwheel or trackpad swiping is fine), the page jumps all the way to the left to the 'top' element. I think it may have something to do with offset. Safari, Chrome and IE8 work great, it's only Firefox 3.6.8 and Firefox 2.0.0.14 using scrollTo 1.4.2

Here is the URL:


Thanks in advance for any clues or fixes.
