When marking images in the viewer, marking them should not give the focus to the marking panel. That would only make sense afterwards. While still selecting/unselecting images, the focus should stay on the image side, so we can use PgUp & PgDown to select images.
Agreed. I too use page up down to go trough images
From what I can tell it only happens when the panel actually opens, is that right?
We'll get that fixed in the next beta.
