Finally got round to putting in a bug report for the problems I'm having with DxO Optics Pro . Their bug report site is only for customers, so here's the content:
Since installing version 7.5.4 of DxO Optics "Pro", I have had numerous difficulties with the interface. In particular:
The "process" window now shows the selected images, very slowly and out of sequence. In particular, the incorrect sequence is very irritating. How can I get it to stop?
Other settings get lost when I stop and restart the program, or when I press F5 to refresh the display. DxO-1.gif shows the settings I had when processing some images. I then removed these images from the directory and put in some new ones. After pressing F5, the settings reverted to DxO-2.gif After pressing ctrl-a to select all images, I ended up with the settings in DxO-3.gif:
In particular, all DxO module-specific processing (distortion, chromatic aberration) has disappeared, and also the crop settings have changed from "Unconstrained" to "Preserve Aspect Ratio". I have tried to save my settings in a workspace, but that doesn't work. It's not clear from the documentation whether the workspace includes this information, but I can't find anything else. Please let me know how to ensure that my settings are preserved from one session to the next.
It's worth mentioning that I didn't notice any of these problems until I installed version 7.5.4.
