[windows] after 30-40 minutes, my shared screen freezes for partner
This has happened repeatedly. Afterwards, attempting to re-share my screen results in showing both partner AND ME a completely black screen surrounded by the green border.
After I give up and use a different program, I have a postage-stamp sized black square that's always on top in the top left hand corner of the screen.
Killing pop via system tray removes the black square.
