I can start Lightroom and import my pictures and when I choose a photo to work with and hit "d" I can work with the photo.
I can also go back to Library Mode by hitting "g".
When I select another photo to work on, and hit "d" again, all I get is the little spinning circle. The spinning can go on for hours! At this point I exit the program and start again. Is this right?
What am I doing wrong?
Which version of Lightroom do you have?
Which operating system : windows or mac?
If it is Lightroom 6/CC2015, go to Lightroom Preferences > Performance > uncheck "use graphics processor" and then, check.
