Loosing session's (really strange)

[olaf]

Hallo,

I have read before a lot of problem's with session's(and cookies) if the client doesn't allow them. In my case it works good on my own page and if a customer use this pages in a new window from his own side. That means he links to my page and open this in a new window. If he link to this page inside his own frameset, then he loose the session. This happens with normal privacy settings in IE 6.0. If i change the settings to low it works like excepted.

How can i solve this problem?

Thanks...
