Nor sure what or how I did, but all the hardware windows now snap into the upper left hand corner and stack on top of each other making it impossible do much. When I try to move a window a a large green 1 appears and lets me move it. but when I release the the left button it just snaps back. into the corner. I tried the two windows options on the menu bar. No idea what the 1st is suppose to do, but didn’t seem to do anything the second item expanded the top item (a camera) onto the full screen with the top half of the window normal size and the bottom half of the window stretched the bottom of the screen.
Problem solved. It was another software for an external monitor which affected the display on the main display and the laptop.
