It used to be in previous versions of Lightroom, that I could export a 5600 pixel width file and set the export width to 5000 pixels. Then I could check the "don't enlarge" button, and at the same time, images that were cropped to less than 5000 pixels would not be enlarged. So larger images would be downsized to 5000 pixels, but smaller images would retain their cropped width. But in Lightroom 5, now if I check the don't enlarge button, then nothing gets upsized OR downsized. Is this a bug???
