Hi,
Just purchased this app and have been exploring the tools for a couple of days now. I've been working on editing a photo for practice and have made many alterations. For some reason none of the healing tools will work on this particular photo. I can choose the tool and take the steps all the way to where it should make the edit and nothing happens. Things I have tried to fix it: Restarting
Restarting with "Control" key and choosing clear
Choosing other photos (this works)
This a bit discouraging as this is the one photo I was looking forward to editing when I purchased the app. It is most likely operator error but can you guide me on what I am doing wrong please? Craig
