And ironically, when I view a picture who's keywords are no longer showing under IPTC, when I look at the checked off "Categories" list on the bottom right, those keywords ARE still checked off, as if XnView remembers them, but they are just not showing under IPTC details on the bottom left.
This continues to happen and I have absolutely NO IDEA why! Needless to say, I am now going to need to go back as far as I can remember and see if this has been happening for longer than I even thought.
Has anyone ever had this happen and if so, any idea why? I am desperate to troubleshoot this issue, as I really rely on tagging my photos so I can find the ones I need when I need them.
Thanks in advance for any help you all can provide
