I have a weird problem, occurs only in IE7, not in any previous version of IE and not in other browsers (tried Firefox, Opera, Safari, Konqueror).

I have a footer on the page (it has no special properties, just sits below everything else on the page) and when the length of the page is dynamically changed, for example when displaying a previously hidden div, the footer does not move down in IE7 but instead simply overlays the new content.

For example on this page: verkoso.com/search/ after clicking search, results are loaded and the footer does not move down as expected. Does anyone know what the problem is?
