I seem to be having an issue closing LRCC, it opens fine and works as usual during editing, import etc. BUT when i go to close it, it won't save anything to the library and just hangs. I've left it overnight and its not a matter of taking its time, its just not doing anything. Im running a 2014 MBP-Retina with 16GB Ram and latest El Capitan. All plugins have ben disabled. Any suggestions other than go back to an older version?
