When I synchronize my folder, using lightroom 5.7.1 on windows 7, I see a dialog box that shows "Import new photos (429)", meaning that it found 429 photos to import.
which sounds ok. But, when I then click the "Synchronize" button, it looks like the import is working
but then it reports that no images were found.
The total number of images in my catalog doesn't go up (currently 34001), and if I repeat the process, I get the same exact results,
namely, nothing imported.
