Can anyone see what might be going on here?
I have been working on the attached drawing for a while and had set up normal architectural scenes. Nothing unusual, successful export to Layout, etc.
In the middle of working on the file, I discovered suddenly that, when I change scene now, it momentarily shows what I intended but then reverts to a fixed camera position. Does that happen to others too?
