Why does rendering to one slot remove renders from other slots? In Cycles render I used to render multiple images to multiple slots to compare results.
But now rendering to one slot clears the other slots.

Is there a setting I need to fix this?  So I can render to all the different slots and the images stay there?
Needed to click the blank button to right of Slot 1.
Then select the render.
It was there, just hiding.
