"Sticky footer on short pages?" puts footer too low

Hi,

When I set the "Sticky footer on short pages?" option to "Yes" it puts the footer below the visible browser window: http://www.haikuniverse.com/

I just started editing this site in Atahualpa with a new WP installation, so there are no custom CSS, javascript or plugins at work here.

Any help getting the footer to be visible in the browser window would be most appreciated...thanks!

Rick
