session value expires with javascript:window.open

Hi,
I have an application that uses session values.
On the first login page,
I am setting
Session.Timeout = 60 'minutes
Session("IsValidSession") = "Yes"

Now while I am navigating through other pages, the session values are fine.
I have an include file(.asp), and here I have a function that redirects to timeout.asp page
code in include file.
if Session("IsValidSession") ="" or Session("currSessionID") =""
Session.Abandon
Response.Redirect "../timeout.asp.

There are two asp pages where the below code is fired when view is clicked.
asp page1.)
"<td><a href='javascript:winPop(""Print"",""PrintPreview.asp?assmtid="1234""",""760"",""500"",""1"",""0"",""0"",""0"")' class=clsUndLink>View</a></td>"
asp page2.)
<a href='javascript:winPop("UNQ","UnansweredQuestions.asp","500","400","1","0","0")' class=clsUndLink>There are unanswered Questions!</a>

Only in this particular scenario, when javascript:winPop is executed the session value becomes null and redirects to timeout.asp, because either Session("currSessionID") ="" or
Session("IsValidSession") ="" is becomming null.

And this doesn't happen in all machines, it happens in some of the users machines only. It doesn't happen in my machine.
I belive the users machine where this issue arises accpets cookies and the reason is if it wouldn't have accepted cookies, then they would have been redirected to timeout.asp page while navigating through other pages.
Please advice me.
Thanks in advance,
Sha.

This is the Lounge. You ahve already posted this in the ASP help
forum. Why have you cross posted it here too...?

Read the 'How to post a question' thread linked in my signature
before posting again...

--Jon.

agree!

I am in very urgent need on this issue, and there it says only ASP Programming, but I thought as this involves Javascript function may be I will post here. Sorry if it is causing any inconvenience.

We know it's urgent. Everything posted here is urgent.

Like I said, read the link in my sig. Just because it is urgent to
you, doesn't mean it is urgent to anybody else here...

You posted your question in the correct place [the ASP forum] -
and people will see it and answer it in their own time [I see there
are already people responding to it].

Cross posting is considered rude and it will not make us answer
your questions any faster.
