Moving to next image - the adjustment box stays live

Not 100% how to describe this. But I'm pretty sure that in versions previous to 13.3, when I move from one image to the next, in Dev. mode, whatever adjustment I made (lets say exposure setting) would lock. The adjustment box would be closed. So that if I hit key 2 for example, to down rate an image (my picks are marked 4 stars), then the 2 would give that image 2 stars. Now it doesn't. Because the adjustment box stays live when you move from one image to the next, when I hit 2, it puts 2 into the exposure number. Not what I wanted at all. 

This means after every adjustment, I have to hit Enter to close the box. An extra step on every single adjustment I make. Extremely frustating. 

Now I can imagine for some people, this behaviour could be useful. But it would be nice to be able to toggle it on or off. Unless there's a method of doing this already, which I've forgotten?
