OH DEAR
I had to buy a new Computer. All well and good except that I could not use the Camera for my Thursday ZOOM conference. I did my best to remedy the problem, but to no avail. So I used my iPad for the Zoom meeting. All well and good . The conference was well worth while. I spent some time this Friday morning to check the Camera settings. Nothing worked well until I realised that the problem was not technological It was Povelogical! I had neglected to remove the sticky tape which covered the computer lens. DUH
