Preview opens previously viewed files
I highlight just one file on my desktop and double click it to see it in Preview. I get a second image from a PDF I view yesterday. Went through Preferences in Preview, but can't seem to figure out how to get to only display one image I select. It's done this before too. I highlight the image and double click and it shows me the highlighte image and the last one I viewed.
