session lost

hi there,

When I did the following steps the session in window A lost.

1.) authenticate user in window A and set $_SESSION['userId']="joe".
2.) open a new window B by clicking a button (in window A) which calls
window.open(..).
3.) I can get the $_SESSION['userId'] in window B (which is what I
want)
4.) When I close window B (manualy or programmaticaly), window A can
not know $_SESSION['userId'] any more.

5.) If I do NOT close window B, window A knows $_SESSION['userId']
without any problem.

This looks like window A passes session info to window B and shares it
with window B. But when window B is closed window A thinks the shared
session is killed.

How can I let window A keep the session even window B is closed?

I am using PHP 4.21 on windows 2000 server SP2.
Thanks in advance!

After step 2 try to add the session_start()

on the top of page B....
