From the back
you can see daylight and the scenery beyond through the upper screw hole, darkness and mystery beyond the bottom hole. These are lined up directly with the problem screw and perpendicular to it. I have tried unscrewing with simultaneous upward leverage from a tiny flathead screwdriver. I also tried screwing it back in, and that had no perceptible result, either. This is getting to be quite the little puzzle.
I suppose that for a PB that came 5 in a box for $39.86 including the shipping, I should be glad things are not worse... :-/
