Has anyone had the same time suck problems? Always something. Couldn't publish to Flickr, now it's FB. Last batch of images loaded all over exposed. I didn't touch any settings......I was gone. I run MAC Yosemite. Personally I think this program sucks. If it weren't for the creative development it would go in the trash.
Scott Kelby's book on LR6 is expected to be on Amazon this week. You may find it very helpful to study a well-structured text book on Lightroom. Many of the "time suck" problems are solved through good basic training.
