I have experienced several crashes when trying to apply multiple control points on an image. Basically, every other time I duplicated a control point it crashed.
A crash submit form pops up but as I am using Windows strictly off-line, I am unable to sent it so I report it this way.
I filed a ticket and DxO asked that I install and submit log files, which I did. I can’t say if anything was accomplished.
Subjectively, I have been able to avoid the issue by closing out PL occasionally then returning to the photo and trying to be more selective about the number of CPs I use. I note others appear to have a similar issue when doing lots of clone/repair edits. Just guessing, but Seems like the programs fills an edit buffer and crashes.
