I'm not sure what I did but I had it so I could click on the icon that split it into 4 screens and throw whatever I wanted on whichever screen I wanted but I fiddled around with some stuff and made it so that now when I click on the app, say I have Firefox open but it isn't on the active page, it does nothing. Whereas before in the same situation when I clicked on the active app it would sling me across to whichever of the four screens it was located on; how do I get back to this setting?
