Yes, I pushed it all the way right just like in Preview. But it does not help. I tried also left and middle etc, but they did not have any effect either.
It works in Preview thumbnail strip. If I zoom a preview it does not pan, instead it changes picture to next/previous depending on which way I scroll. If I change the sensitivity for Preview to left, then it stops working there as well.
edit:
I found the pan/advance selection from Preview preferences, and if I change it to Pan, it does not work while I have zoomed into a picture.
