I seem to have unwittingly activated the Survey mode in Lightroom Classic and cannot close it.
I have the usual Lightroom interface and you will see that towards the bottom, the icons are Grid, Loupe, Compare, Survey, People etc.
On my second screen I have an unfamiliar interface showing tabs at the top for Grid, Loupe, Compare, Survey, and Slideshow. This window fills the screen and does not have a Minimise, Close or X option.
I found in the View menu the option Survey with the shortcut N. However, N does not seem to toggle it or affect the second window nor does unticking it the menu option.
Any ideas as to how I get rid of the second window?
