Kirk,
When I filter on Keywords, such as "Concerts" (shown in screenshots), the resulting contact sheet shows images that have nothing to do with concerts, and I can't find any data in the metadata panel to cause them to be included.
I'm using structured keywords only, and this particular keyword is in the form of Concert | performer, where performer is replaced with the performer's name.
When I select "Concert", I get what seems like extra images in the result, but if I select from the perfumer part of the keyword structure, it works perfectly. If I then go back and select the first level (Concert) again, then it works perfectly as well.
This issue started with R3663.
Confused...
