Not working 100% on Internet Exploer

Hi,

Sweet Captcha is working on all browsers except for Internet Explorer on my site http://wakeup-world.com. Im currently using IE v9.0

It is not loading the main image to drag one of the 4 options across to.

It also is displaying 2 submit comment buttons.

Any help would be appreciated.

Cheers

Ryan
