Share Screen does not allow choice of application window
I have been seeing an intermittent issue with Share Screen. I am the host and usually when I click on Share Screen I see several windows that I can share, most of which are application windows, for applications I have open such as Word or Acrobat Reader. But yesterday in a class I was teaching, I saw only three choices: Screen, Whiteboard, and iPhone/iPad. I have seen this issue at least once before, but I am not sure what is causing it. Can anyone help? Thank you. Mark
