When I hit Develop, the middle box is blue with an X in the middle. I don't know how to remove that so that my pic is in the full screen? Thanks for your help.
Please go to Preferences>performance>uncheck "Use graphics processor".
Restart Lightroom and make sure to update Lightroom to the latest version 2015.6.1/6.6.1.
Thank you, Thank you!!!
