Missing libraries?

What makes you think this has something to do with missing libraries?
I can’t figure out what some of the problems you list mean, e.g.:

  • can’t select a particular photo - what does that mean? When you double-click a photo, the darkroom is not activated? Or you cannot make a selection, like you would in a file manager, to perform operations like copy/paste history stack, remove/delete photo etc?
  • can’t apply “styles” up front to a variety of selectable slides - what do you mean by selectable slides? And by apply[ing] “styles” up front?

Could you please perhaps post some screenshots? You can paste them directly into the message editor.
