I use the pent tool to make a shape, then right click make a selection, I fill in the selection with the colour I want. Great perfect no problem.
Now say if I want to go to the stamp tool and work on a different area of the picture, the previous selection from the pen tool still exists, and I can’t use the stamp tool. I cant seem to figure out how to get rid of the previous selection.
Just click inside the selection area with one of the selection tools. Alternatively, try
Select > Deselect.
