This issue only occurs in IE, when I click a tab increases the height of the page, the footer placed below it doesn't get pushed down, it remains in its initial position, overlapped by the additional content from the new tab. Here's an example, click the specs tab in the bottom quicktab set - http://microstrain.com/inertial/3dm-gx3-45

I'm sure its a CSS issue but I can't get anywhere with it.
