Hi Brian – Well, it wasn’t exactly like this. When I changed the view in the upper right to Top view – The one upper left did exactly the same.
But I did eventually find this out by myself –>
The “real camera” in this scene was called “Ocean Camera”. The way it turned out was that BOTH the upper views were set to -> Cameras/Use Camera/Ocean Camera.
When I changed the upper right Camera view setting to “Default Camera” – and kept the upper left at “Ocean Camera” – it worked normally in the upper right hand view – when selected as a Top view.
I think it was actually a plugin (with a camera, “Ocean Camera”) that had set both the upper views to “its own” camera.
The “error” was very peculiar and confusing when jumping between different fullscreen views by F1, F2, etc.
