When I got this computer I was having trouble with double posts. It is windows 10 with edge. At that time several folks were having the same problem. It would happen after I had entered a post, I would just hit the back button to return to the forum. That was causing my double posts. Since then when I make a post I just reopen the S&W forum site and go to the subforum I was originally on. Seems rather awkward, but I don't get double posts now.
