I have implemented a java scrollbar to a website for someone i know, as far as i have tested it works perfectly in safari (mac), firefox (mac + PC). In IE however only two of the three gallery pages seem to be working. even though the code is the same. I was wondering if someone could look at it for me?

Thanks in advance, the site is http://www.melsimages.com
The gallerys that seem to be working are
www.melsimages.com/photo-parties.html
www.melsimages.com/portraits.html

the one that isnt working in IE is
www.melsimages.com/gallery.html
www.melsimages.com/fairy.html

(gallery and fairy are the same just lazy coding )
