TLE Small Dome multi monitors screens go black (OSX)

    1.  Plug in the second monitor.
    2.  Go to System Preferences ---> Display ---> Arrangement ---> uncheck  where it says "Mirror Displays".
    3.  Try TLE Small Dome.  It should work now without the screens going all black.
    It is checking the setting to "Mirror Displays" that causes the screen blackout when TLE Small Dome is initiated.
