For the most part I am loving the new version of LR. One issue I've noticed is that when I switch from the Develop module to the Library (grid) view, a large black box appears in the image area, and there is a significant delay. Very often the spinning beach ball appears.
I am on a fast 5k iMac with my photos on a LaCie Big drive, running LR 6.0.1.
Thanks for your help.
Really? No one else is experiencing this? I've read about it elsewhere... surprised if I'm the only one.
I was very disappointed to see that this wasn't resolved in the 2015 CC update.
