A month or so ago I updated LRC to 12.2.1. This evening I stitched a panorama and needed to fill in around the edge a bit, but found that the healing tool has stopped working. I can select the area, and the healing fill shows up, but that's it -- the action never completes and the spot remains unrepaired. Opacity is set to 100, I'm on Windows 10.
I just ran an update to 12.3, rebooted the computer and opened LRC -- the problem remains. I opened another file and went to "Visualize Spots", and got the same behavior. I did a lot of printing before Christmas with the previous version of LRC (11.x.x) and the spot healing worked as intended. Any ideas how to fix this? I thought the new update would overwrite the old install, but whatever is causing this is persistent.
