Hi, I'm trying to Skype with my grandkids. I get the connection, can see and hear them, but they can't see or hear me. I get a note that my camera is being used by another app. I often get messages that my camera is being used by ____ , and tried to stop access that I wasn't AWARE of, but am still GETTING these notes. New here and not very GOOD with computers. Am I even in the RIGHT forum?
