The only section of Lightroom that I use is not working at all. I don't know what changed the settings. When I am under the mask section, I can't change exposure, saturation, etc. by using the sliders. The picture stays the same. I also had an auto box that I had checked off and that disappeared too. Please help. Thanks!! Elaine
What do you mean by 'mask selection'? Are you working in the develop module's, basic panel? Do the sliders not move at all, or is the image not changing when you move them? Can you post a screen capture of what you see?
If you are using one of the selective adjustment tools, press H to hide the mask and then use the sliders.
