Two questions. First why does LIghtroom always display that one photo still needs to synched? Even after synching 400 photos, it still say that one remains. Second, I was attempting to synch about 400 photos and my network was very busy and the speed very slow. I kept getting a message tha Lightroom was unresponsive and assumed it had crashed. The synch was running VERY slowly and when I selected teh collection that was being synched, it went grey and I got the unresponsive message again. The synch completed once the network became less cluttered, but the behavior seems weird.
