Eraser tool. 2021 Ed. I used the eraser tool and no checkerboard squares
I used the eraser tool and got this wierd blurring action and not the checkerboard squares. I saved and closed the file. Then I researched the community posts and learned that I should have unlocked the background layer. So I opened the file, unlocked the background layer and tried again. Nothing happened and no checkerboard squares. Can this be solved? I saved a few prior versions, but don't want to start over.
