Follow up, only occurred after running "Simple System" and reboot. Subsequently found that although Chrome would not run in "normal" mode, it would run if right clicked and selected "run as administrator". Seems as though "permissions" were changed? I turn off system in the evening, when rebooted system this A.M., back to normal. Probably just a coincidence? TKS for the post. We find the "all in one" to be a valuable tool.
