Camera RAW: Arrow keys to select next image are not working after using zoom function

I open several raw files in Camera raw and click through them using the arrow buttons.
I use the mouse to zoom in to 100% and back out.
Now the arrow buttons don’t work anymore unless I make one extra mouse click into the film stripe area.

One extra click sounds like a minor problem, but when you select hundrets of photos, it gets a lot…
