Facebook recently changed a little bit, and that affects how the auto-login works. What's happening is that the first time a user visits the page with an active session, a cookie is set (by Facebook) with that user's information through Javascript. That Javascript happens -after- the page has rendered, which is where JFBConnect tries to auto-log the user in. On the next attempt, JFBConnect is able to then see the cookie and auto-log the user in.
We're looking into a Javascript fix to make it work on the first page load.. basically, the page would render, cookie would be set, and then the page would have to reload to let JFBConnect auto-log in. We're looking into it for the 4.0 release later this week, but it may not be implemented due to required testing until the release after that.
Hope that helps explain, and sorry for the inconvenience,
Alex
