When using LR cc, when I switch into PS very shortly my wireless keyboard quits working. I have to restart to get my keyboard back.
I have noticed, if I minimize my LR immediately after going into PS, my wireless keyboard will continue to work after closing PS and going back into LR cc. It appears to be a memory problem, I have 16 gigs memory, and a SS main drive.
I'm also using El Capitan. Ive not noticed my keyboard quitting in any other programs
