Update:
Apple's development engineers have now reported the problem with the Retouch tool as widespread and are working on a fix. Let's hope it comes soon.
Update:
I finally heard from Apple that there are others having the same issue and they're working on a fix. That's actually great news because there's nothing wrong with any of my files. In the meanwhile I'll just have to limit my use of the Retouch tool to simple jobs, like removing specs rather than major jobs removing such things as power lines.
