Membership pro / popup pro / facebook connect login form issue

I created a popup (popups pro) on a "join now" button that displays a membership pro registration form. I was hoping to also add a facebook connect icon (using ultimate facebook) for the user to optionally login with facebook. The markup for the facebook login button is being created but the button is just text and is not clickable. Can this work, or is the popup interfering with the javascript to fire the facebook button?
