I believe I have the answer. I am using a program called Ghostery, which blocks analytics, trackers and the like. If I use it as a browser I get a security block when logging on to the forum site. It will not allow me to save any log on to sites that use trackers. It was never the cookies setting. Not sure if the trackers are generated via the HSXS logon, the ISP I'm using or the browser .............
Thanks
