Weird: Selected Scene changes to other scene when clicking other app


New Member
I have a new issue, never noticed this happened before.

For some reason when I am in OBS and I have a scene selected, if I click in another app, let's say notepad, OBS reacts by changing my scene to another scene, Scene1. (Let's call it that!)

Strangely, it's always the same scene it changes to, Scene1.

I tried with other scenes being active and selected and then, sure enough, when I click in notepad OBS changes my scene to the Scene1.

What setting did mess with that would do this?

So far I tried looking at hotkeys but that doesn't seem to be it.
