I have a page which updates a section of itself via AJAX when a user clicks a link.

It all runs smoothly in Firefox, IE8 and even IE6 but IE7 doesn't seem to update the size of the page when the AJAX is complete so the footer remains at the bottom of the viewport as opposed to the entire page.

I know there's a javascript workaround for this by getting the page size and setting a new container height in pixels as opposed to percentage but it screws up when say a user hides their address bar.

Does anybody know how I can fix this?

As anybody who runs this in IE7 will see, upon expansion the footer will remain at the bottom of the viewport, instead of the behaviour of every other browser which moves the footer to the bottom of the page
