I set up Lightzone as an external editor in prefs. I select a couple of photos to edit in lightzone and I am only able to get one photo out of selection to open up in LZ. I am selected the option of "editing selected images". I have a request in with LZ also because I'm not sure it's an issue with them or PM.
Thanks
