I've recently been infested with a drop-down box on some Safari pages which tells me that "Safari can't verify the identity...etc", and with options to "Show certificate", "Cancel", or "Continue". The name on the designation is different each time, and often pretty weird. Usually, if I click on "Continue" - it does, and the box goes away. If I click on "Cancel" I don't get the page I want! What is this please? It doesn't seem to be anything I need to be concerned about, other than irritating the hell out of me: but is there a setting somewhere that could obviate its appearance so often?
