@ Y-Phil, ghostman ; working on other settings that should NOT affect that but might be. Got a single V4 Mick rendered using 'render over current bg shader' and it didn't activate that POST thing. It did both of these without hooking POST. I am leery of clicking that symbol in the render screen, that might be what sticks it on.
