When I am in either of the above two modules and I am moving from photo to photo with my mouse, eventually Lightroom CC will stop responding (I cannot select/reorder photos) and I have to close down the program. I've shut off the GPU accelerator but that has no effect. What can I do to stop this problem? I am running a 2010 MacBook Pro.
How much RAM in the computer? What operating system are you using?
Jim, thanks for responding. I have 8 GB RAM and am running OS X Yosemite.
