Rick,
I'm a novice when it comes to cookies, however I managed to trace this to the rotating banner scheeme that i'm using. I have changed all settings for that software to http:// instead of
http://www.I was adviced before to set a .htaccess file to rewrite all non www urls to www.
I have removed that .hraccess command now.
It looks promising after an hour I have personally not been logged out my self.
Knock on wood I'll comment more later on
thanks for your help sofar, much appreciated!
