This has been driving me nuts for over a year and I'm ready to do something about it. I use the Modern IE in tablet mode. I rarely have the keyboard attached. Whenever I open IE it opens a lot of browser tabs I had previously closed. The net effect is that I rarely have less than 30-40 tabs open and it does no good to close them, next time I use IE they all re-appear! Someone have mercy on me and help me fix this aggravating behavior!
