When activated, both the GPS screen and video screens display in the wrong place. They are correct size, but located in the upper left corner of the screen. If you enter full screen, then return to normal mode, they are then in the correct position.
Also the GPS window (iGuidance for me) displays the menu bar ("file" "edit" "view") in both windowed and full screen mode. I don't know if this is a new or old problem.
