Some pictures do not show the thumbnail in the Gallery view. When I open them in the Edit view, they show just fine. Some are scanned photos, some are not. Nothing is too large, they are less than 2 MB in size. I checked to make sure that Hidden was not checked, and it wasn't. I have re-started Photo Gallery and re-booted the computer. Neither helped.

Any ideas on how to get these to show up? Thx.
