With Java update 7 installed , the courses in my LMS launch fine. when I update Java to 10, 11 and or 12 ,the launch page hangs and then I get a Title Manager Signed Applet pop-up window that states: "Security Error, unable to send request.This course must be loaded from the system that the data is submitted to: denied access outside a permitted URL subpath"Can anyone give me a morsel of a clue as to what is going on here?
