I'm using the paint.net clone stamp for the first time. I've done cloning before, so I'm familiar with the basic process. The problem I have is that instead of a single circle copying and pasting (as it were - I don't know the stamp tool equivalent terms), I have two circles, one with a little + (cross hairs?) inside. One seems to do the copying and the other the pasting. When I move circle w/+ to a new spot, the other circle moves, too. When I copy, what gets pasted is the section the other circle now occupies.
How do I get rid of the second circle? It's like a reverse torture of that annoying kid who followed you around mimicking everything you did.
