Thanks gog. Tried your suggestion- still no luck for me.

The 770 was set on London time and I'm in California. I switched it to California and DST rwhich eversed the Month and Day part of the date - to what we would expect in the U.S. - but still no luck on the two secure web sites.

It rebooted after switch. And I also rebooted it again just for good measure ...It's been very reliable otherwise.
