Mad, I had been to that location a few times and I thought the highlighted BRUSH SIZE IN TOOLBAR was about the brush size (1,2,3,4...etc) that is easily seen on the toolbar and I had no problem with. There was nothing to click on about brush shape. I also went to the tutorials and searched on CLONING but there were so many subjects to have to read through.
Even when you gave me the link that I had been to so many times, out of despartion I then clicked on BRUSH SIZE IN TOOLBAR and was surprised to find the info I had been searching for. Sorry, but for a novice, it was a had find. I wasn't being lazy and would have gladly read up on my own but couldn't locate the info. Thank you, Paw
