Yes, it does trigger it.
(I had to remove session_start() because that added another warning
since I had autostart on on the machine)

Aha, now I get the error.

Let me summarize: PHP is wasting time by checking if I use variablenames
in my script that exists as a key in the $_SESSION?
Jeeez... What a waste of CPU resources. :P

I am surprised I never had this warning before, since I NEVER paid any
attention to similarity in names in SESSION and my scriptvars. ;-)

Thanks Rik for your clear and fast reply.

And yes, very lousy description of the error/warning indeed.

I'll immediately change the php.ini to surpress these nonsense warnings.

Thanks.
