since the update to lightroom classic CC (from lightroom CC) I do have the problem that the switch from the library grid view or single picture view to the developing view or model fails (dark main screen but active editing sliders) . It seems that all editing sliders are active and translate the changes into the picture. I can see the changes in the filmstrip at the button, but the main screen is dark and doens't show the picture.
Does someone have an idea or proposal how to solve the problem?
Thanks in advance
Helmut
