Session problem

Let's state down the problem before proceed on:

Browser list:
==> IE6 (1st browser window)
==> IE6 (2nd browser window - open by pressing Ctrl + N)
==> IE6 (3rd browser window - open by double click on IE6)

Problem:
I try to refresh 1st IE6 browser window a few times to increase the value in
$_SESSION['count']. Then I press Ctrl + N to open another browser window
(2nd window) and point to the same URL and refresh a few times. OK, the
value in $_SESSION['count'] is incresed. But problem occur when I open the
3rd IE6 window (by double click on IE6) and point to the same URL. The 3rd
browser window start another session and the value in $_SESSION['count'] is
begin from the initial value - 1. I can't get the value in 1st and 2nd
browser (since that is another session).

My question:
Is there any solution to solve this problem? I'm going to use the session to
do login function. But if I can't get into the same session, then my login
function would have a defect issue - need to login again when open new
window by double click on IE6.

Thanks for suggesting a solution.
