My LightRoom CC is not responding. When it does, it takes minutes just to set a rating or change modules or even zoom in and out on an image. And once I do a command like SET RATING, the 'setting rating" pop up isn't going away. Seems like a huge glitch in the LRCC My new Mac desktop is only weeks old so I know there isn't an issue there. It just started doing this today. I shut down the program and backed it up. That didn't fix it. I restarted my computer and that didn't fix it either. HELP!
