"reopen all windows from last session" not working properly
Sometimes I will hit a wrong tab and lose all the tabs and pages I am working on. But when I hit "Reopen All Windows from Last Session" in History, I either get pages from months ago, or some nonsense that Apple is apparently trying to get me to buy. All I want is my old work up. How can I get them back quickly and easily (which is what I thought "Reopen All Windows..." was supposed to do)?
