I thought I better give you more information so you can advise me on this problem.

At my show, when I started up the laptop, the Hoster desktop came up on the singer's TV display, and on the laptop. I then entered the Hoster program, and put a song in the playlist.

When I went to play the song, the desktop remained on the TV, put on my laptop, the preview screen, with the other screen on top of it, played the song normally.

After I restored the computer, the Hoster desktop came up as usual on TV and laptop, but when I entered Hoster program and played a song, all was well.
