I just upgraded last night and imported my first group of photos, around 100. On previous versions, I would double click on the first photo to open it in Preview and then use my arrow keys to move to next photo and the "t" key to tag the photos I wanted to keep. This was quick and easy to cull through large amts of photos. I cannot do that in PM 6. For some reason, I cannot tag photos in Preview mode, I have to go back to the Import screen and click on each small box with my mouse to tag the photo. I am sure I am doing something wrong, but I just can't figure it out. I could get through a couple hundred photos in 5 minutes in PM 5. Can someone help
