Sidebar at bottom in IE7 but not IE8, Firefox, Chrome..

Unfortunately for some reason in IE7 my sidebar is sliding down to the bottom of the page; this doesn’t happen in IE8 or the latest Firefox.

I’m not the best CSS coder in the world so I’m sure I’ve hacked something up along the way. I’m just re-tooling the default theme.

If anyone has any ideas I’d be grateful.

Cheers
