I've been having issues with the Lightroom sliders not working. Yesterday I noticed when I started Lightroom none of the sliders would move. However, when I double clicked on the slider name it resets to zero, I can move the histogram, I can use the spot removal tool, etc. but no sliders would move. This morning the sliders worked again. Tonight none of the sliders will move. What is going on? I have the current version: Lightroom cc 2015.2.1 (1046594).
What is your Operating System?
Please restart your Computer
Also backup your Lightroom catalog and reset Lightroom Preferences .See Resetting Preferences in Lightroom CC/6 | Lightroom Blog
Let us know if that helps
This problem only happens periodically. It has happened 3 times (the third time was last night and this morning everything is fine again) over the last week and a half.
Did you tried what I suggested in my Previous post?
If you did and issue is still the same ..then, create a new catalog and import few Pictures,
check what is the Outcome and share the same with us
