When exporting photos, once 3 errors have occurred (due to missing watermark files in my case), the export simply hangs indefinitely and has to be cancelled.
This is easy to reproduce.
- Open a folder of, say, 10 images.
- Set a watermark image on 3 of the images.
- Move/rename/delete the reference watermark image.
- Export all 10 images.
I also note there are serious layout issues when errors occur and the export dropdown only has the one export batch present.
