Not sure if this was a fluke or what but I expanded/enlarged my programmer window to see some details on the screen and when I went to restore-down to the normal window size it would not restore down. I tried both the trackball and the touch screen on my M1HD and the programmer window was locked/frozen in its expanded state. I could bring up other windows on top of it such as the system settings/menu but nothing would exit the full size window screen and the blue expand window screen kept flashing.
I finally had to reboot the console to get the main internal screen back to normal operation.
