Hi, I've got an accordion style menu system. It's all working fairly well, except that when the page loads all of the sub-menus that should only be visible when the parent link is clicked on appear, then disappear a few seconds later.

You can see an example of this here:


This may not be totally clear here as this is a stripped-down version of the page - the effect is much more pronounced when it has the rest of the page and all of its images, sIFR etc to load.

Any ideas?
