so my cat jumped up on my keyboard while i was working in lightroom and it isn't working properly as a result. I have no clue what happened, as the cat is big enough to have covered the keyboard completely. Most of my brushes are either no working, or not working at full capacity - they seem to be so faint that i can't tell that i have done anything to the image. You know how you press the O key to highlight your recent work in red? Well, now that isn't red, but instead a very pale green. Help!!!
Shift-O a few times will turn the overlay back to red
Perhaps the brush Density or Flow is now set to near zero?
