Jquery, Tabs, CI Forms, and page refreshs....

It's most likely the jquery plugin IMHO. BUT...you could use firebug to determine whether CI returns a 301/302 redirect to confirm.

EDIT: actually, a redirect would reset your page. Definitely NOT CI.

EDIT AGAIN: Sorry, I guess it wouldn't since the whole transaction is handled by ajax, but you should still be able to tell from my first suggestion.
