Thanks for the quick reply. I appreciate it.
I understand now that the big white space on the right is for video. However, this screenshot is the "before" photo. The image in the middle disappears off the screen and that middle image becomes an empty space. I believe you are telling me there is a setting that I can use to adjust this - something to do with the box - front priorities. I don't quite understand what this part means. I know there are settings (an overwhelming amount of them), but I can't quite seem to make sense of them in the way you have described. If it's not too much trouble, could you possibly rephrase your advice so that I can get it through my (somewhat dense) head?
