So in preview when you "exposé" it gives you a row stuff at the bottom of images and such that you previously had open. How do I clear that? If I go to File > Open Recent > Clear Menu and click that it clears that list. But the row of previously viewed stuff on the bottom still remains. Is there a way to clear that also? The only I've seen that will do it is if I restart my computer. If I "right click" the icon in the dock the history is still there.
