How can I stop Directory Opus from opening all my photos in its own viewer? I can't seem to figure out where to do this in the settings. I want them to open in Windows' own Preview.
Also, (and this is the main reason why I don't like to use the built-in photo viewer) is there any way to make it possible to advance through my pictures with the RIGHT & LEFT ARROWS? It is really unintuitive to have to click on the space bar and/or shift space.
