FR works fine in some cases, seems asleep in others. Usually this happens between folders (pix in some folders have FR, pix from some other folders do not), but sometimes *within folders (some pix have FR, some do not). I am speaking here of photos of similar clarity. I would not expect it to recognize some of the fuzzier photos I have.
Second question, in backing up my catalogue, as a precaution, I have backups done at different times (1, 2, 3, 4). I thought if one went bad at least I would have an alternative. Reading some of the discussion around FR, this might not have been wise? If so, how would I fix this?
