Only Half of My Library Loads
When I open Lightroom I have hundred of folders. They all displayed in alphabetical order but when I scroll down to "T" any of those folders from then on I can't click on. They are all visibly there but I might as well be clicking on a blank space as nothing happens. I have tried to optimize the catalog, I've updated to the latest version, and I've restarted my computer. It still won't let me click on anything past the letter T. Any ideas?
