Facebook Connect Plugin

I installed the Facebook Connect Plugin for MovableType. Its supposed to allow you to login using Facebook credentials and share the comment back to your Facebook wall. The login seems to be working sort of ok in Firefox (once I allowed all the Facebook javascript to run). But in IE, its not working at all. I’m not sure if that is because I am using AJAX comments or if its caused by something else.
That is the state is going to remain in for a while.
