I want the ok-looking image(s) and the too-red image in the same screenshot. I only see Lightroom in your recent screenshot and everything looks ok, the thumbnail, the Navigator preview and the main Loupe view.
In your first reply to me you show a thumbnail that is redder than the more recent screenshot. What application or program did that thumbnail come from? Can we see a screenshot with that thumbnail and the LR view at the same time, with Window title bars so it's obvious what window is showing the ok-looking images and what window is showing the too-red image?
