cool. you and i were talking about two different things. you are using
__sleep and __wakeup by issuing the serialize and unserialize commands
yourself. i am using __sleep and __wakeup when php automatically issues
them itself when using sessions.
it is my experience that if you have an object and you register that object
as a session variable, and you do _not_ have a __sleep function, then
everything works fine. this is different from having a __sleep function and
not returning anything (or the wrong thing)
