dual monitors

[Rchjr]

Hi there, I use 2 monitors when editing. All of a sudden when I am in lightroom my other monitor is now showing  screen that has grid, loupe, compare, survey and slide show showing. How do I stop this from happening. I dont want anything from lightroom showing on the other monitor. I have no idea what I did to start this. Any help would be appreciated.

Thanks

Also, everytime I go to click on one image in the slide show of images imported instead of chooseing 1 it does 2. 

What in the world is this?

Thanks

Toggle a second Lr screen with Function key [F11]

or click on the [2] icon lower-left of main screen-

 I do not understand your next comments- "instead of chooseing 1 it does 2". Can you explain in more detail?
