My screen in the Develop mode is now blue with a white x on it...I can edit but it only shows up in upper left corner. How do I get my photo to come back to the large main screen?
Please go the Library Module, then go to the Preferences.
Please go to the Performance Tab and uncheck the option for " Use Graphics Processor"
Restart lightroom, and see if you are able to work in the Develop Module.
Please let us know if it helps.
Wow, I never would have figured that out.
You are Welcome, Glad to help.
