What's happend? what do you try to do?
I was attempted to use the quick select tool to make an selection. After making the selection, I made a curve adjustment layer. I then selected the mask from the curve adjustment layer. I was trying to refine the mask by using the select and mask feature. After picking the refine edge tool, I tried to select the edge of the selection. Would not work. Appears to be grey out.Thanks
