I was working with the repair tool recently a little bit more than in the past. I have found an issue/bug that is pretty annoying and time consuming, not sure if it was reported before.
I was repairing certain areas in a picture at 200% view.
After a while I decided to repair more areas, so I switched back to 200% view and clicked on the repair tool again. However, all ‘old’ repair masks have shifted. You can clearly see it at the top, where the repaired areas (cigarettes or something else) have reappeared, but also in the other parts of the image.
You actually can start the repairing from scratch. The shift however will always occur if you come back to the repairing tool as if Photolab is not recognising the position of the repair masks properly in accordance to the magnifying percentage. I am using the Mac version by the way.
