Topic: 2.0.1: _SESSION variable
First, there's a "caution" listed in the PHP documentation that advises against mixing _SESSION usage with session_register(), session_is_registered(), and session_unregister().
http://php.net/manual/en/function.session-register.php
Second, I think it would be a wise idea to use a namespace for FA's global variables. I ran into some anomalous behaviour which I now attribute to being a conflict between FA and WebERP running on the same server and evaluating both systems concurrently in separate tabs of a single browser instance.
