[Zope-CMF] CMF logs user when changeing to a subfolder

[Robert Rottermann]

Hi there,

I developed a site with CMF for a customer. (V 1.1 upgraded to 1.2, Zope
2.4.4b1)

On the customer site (meaning working from the customers building) the
CMF-site logs people out when they change to certain subfolders.
Also people can not cut and paste elements from one folder to an other.
After cutting an element in the source folder the "paste" button is visible.
But not after they have changed to the target folder.

I was wondering whether this has something to do with cookies?
The users are behind a firewall.

thanks for any insight
