Earlier this morning, I added photos to the profiles which previously had no photos. Both were pages from high school yearbooks, and in both cases I used the "Identify" feature to select a box, so that the profile pic would show as a "head-shot". After I clicked "Done Identifying", things looked OK; I could hover over the selected area and the person's name popped up as expected. But.. once I exited that view and reentered, the identification had disappeared. There were no activie identifications on the picture.
I have used this same procedure many times, and it has worked as recently as yesterday, for other profiles, of course.
So, if this is a but, it was introduced recently.
