Two displays instead of one

[dlessnau]

I made a user account on my computer to play the Hoster songs. When I play a song on the laptop and am not connected to a TV, I get a full size picture as the song is playing. If I click on the screen I get two small pictures. Why?

If I use the administrator account to play on the laptop,it is normal. first the full screen and a click makes a single small screen.

I have not yet started up the laptop in user mode while connected to a TV, so I don't know what will happen when I do that. I will find out tonight at my show. The set up is the same as far as I can see under screen properties.

I suspect, I will have a problem when I hook to a TV, getting the picture right on the TV and only showing one picture on the laptop as a song is playing.

Any advice?
