Beavis,
The reason this happened. Since you did not have your Second Display attached, it went full screen on the single display.

NEW - Dual Display - We made a change to make this more reliable. If your Video Card shows your primary monitor as number 2 and the TV as 1, prior versions would not go full screen on the correct monitor. It would jump back to your Desktop. You would then have to drag the screen to the Tv, and stretch it out to fill the screen. You now can double click and we will match the Primary screen so that we always find the intended singers monitor.
