Hi, this is not working on AD, AP and APub so i think this should be a small bug.
If you open the character or paragraph panel (don't know if the others have the same behaviour) and the scroll bar appears on the right, if you use the mouse scroll wheel to scroll through the panel nothing appens, if you move the mouse cursor over one of the items it work on that specific item.
Hope i've expalined myself. I could post a video if needed.
