Session Problem

Hi I ve a Problem when i try to use sessions. I can do destroy_session() and at the next time there is session without starting session_start(). I closed the browser and startet a site which only does: <?php echo $PHPSESSID; ?> and he shows me a session id without having a anything in my session.save_path :( when i upload the sites to tripod everything workes fine. Seem's so that there is a misconfiguration at my php.ini but i don't know what the failure is. I hope someone of you has an idea. tnx mySTYX
