How to automatic log-in after user "Register" with FB connect through Ultimate Facebook?

Hi,

After using "Register" page with FB connect (through Ultimate Facebook plugin) to register, the user will not be logged in. In the other hand, if the user use "Login" page to register as a new user, he can be redirect to any page I want by setting it in the plugin setting page.

Is there any way to automatic log-in (or even logged-in and redirect to a page) after the user using "Register" with FB connect through Ultimate Facebook?

It's important to me, and confused me for a long time, please help me.

Thanks!
