[Zope-CMF] Error:logged in user changes wen chnging folder

[robert]

Hi there,
I have a strange error.
I am testing a CMF site.
For test purposes I log in under various user names. (all have the same 
password). Now when I click on a folder:pop I am manager, I go to the folder 
I came from:pop I am the "authenticated" user again.

I am using Mozilla 1.4 under Linux. However this seems to happen under IE6 
also.

Any help is greatly apprecheated.
Robert
