LIGHTROOM: reject "X" has lag
after i import a shoot, i quickly edit it down. using either auto- and manual-advance, the reject flag does not apply quickly enough, so sometimes it skips the foto displayed as a single image in library altogether, and sometimes it attaches to the next foto. so instead of ending up with the, say, 20 shots i want to keep out of a shoot of several hundred, i end up with 50 or 60 un'reject'ed shots. and then some shots i wanted to keep have been marked rejected. so i have to work very slowly and double check. and that is really tedious. it's kinda like shutter lag. i am working in lightroom 4.2, windows 7 and have lots of ram and speed.
