I had a queue of 4 black and white images to upgrade. The first image is improved as usual. The second image gets stock in an endless loop. When I saw that, I closed the application and in an additional session I started the update process with second image. This time the image got improved as expected (time and quality). The third picture, now second on this session repeated the same undesirable situation. It got stuck in an endless loop. I repeated the closing of the application and reuploading the image. Same result: The first image on the queue gets improved as expected. It worked very well. When processing the second picture in queue it got engaged in an endless loop.
Note: When trying to use Crop with one of the images that got upgraded, the “Crop” option did not work.
