JFBConnect Fan Box not working in IE

Hi,
I have an issue with the Fan Box not displaying in IE 7 & 8.
Firstly, I will always try to avoid frames, but I have no say in this particular instance.

The module isn't rendering in IE 7 at all, and in IE 8, it doesn't render in a frame.

Could it be mootools?Webpage error details

Is this a known issue for anyone else?
It seems to be working in other browsers?

Could it be related to this: www.sourcecoast.com/forums/topic?id=1198

I can PM the two URL's, if someone can take a look.
