freitasm: It must be something else - perhaps you have an AV that is cleaning cookies, or your browser is set to store cookies for the session only, or a proxy causing this.
I know for certain is not our code because for the last four days I have an email trap that notifies me of sessions being logged out due to IP change - and YOURS IS NOT SHOWING UP IN THE LIST.
No need to yell.
Linux notebook, no changes since the log outs have started happening - and it's literally being put to sleep with the browser left open, then when woken GZ live won't update my "participating" threads, and if I reload the page, the header reverts to a logged out view. Of course, it's being woken in a new network environment, so that'll be where the red herring is coming from.
Hey, I'm not saying it's definitely the site code, it was just a thought towards a possible cause.
