I need help to clean up my site

Hi, basically I’ve finished a site, but have a few issues with XML data loading, reading one article then going to the next one and it still being scrolled down from the last article for all the sections.

The sections themselves are in movieclips which are either visible (true or false) and load the XML when first viewed.

Can anyone help me with this problem, I will post Action script is its needed, is there something like a clear XML cache script or something along those lines, thanks for the help in advance.

The site can be viewed at http://schools.trewitleyowltrust.com (may take a while to load)
