If you are like me looking for a way to close the gps window with a mouse instead of looking for the icon to click on I have found you can put a transparent gauge on the main screen allowing you to close the window by just clicking the screen. Just open the panel.cfg and place this gauge in the gps window may need to adjust size and location a bit depending on the aircraft.
gauge01=cpt.icons!GPS_T, 33,40,340,250 // added lkw
the gauge number is the next in sequence this one was taken from the default mooney bravo
