Summary: I can no longer see the circle outline of the patch tool brush. How do I get it back?
Details: I was using the patch tool, with a circular brush that I could make larger and smaller with "]" and "[", and using alt-click to select source region, etc. Then, somehow, I must have done something, and I can no longer see the circle outline of the brush and the patch tool. I've searched the help and forum and I can't see what I've done to switch modes. Please help me figure out how to get the circular patch region to show again when I am using the patch tool. I think it is in a mode when it wants me to click and drag to select a source region.
