Hi, first of all, thank you for the wonderfull program. I think the face recognition is best of all program’s I tried. I’m working with the program for a couple of weeks now. I noticed tags cannot be assigned sometimes. I discovered a differences in the files that can be tagged and those who cannot be tagged, could it be a png-file that cannot be tagged? I also noticed a png-file blocks the selection of multipele photo’s at once by means of the shift+click strategy. Am I wright and can this possibly be solved?

Update: same for dng-files?
