FORUM ISSUES: Report Upgraded Issues in this thread

After a couple weeks of excellent behavior, the forum has started backsliding in the last few days. Several recent posts got posted, but then took me right to the Advanced post page, or perhaps the edit page (I don't use either enough to tell them apart). If I were to hit the Submit button on whatever page that is, I'd end up with a double post. This must be happening to others, too, since I'm seeing LOTS more double posts lately, including an impressive triple post (you have to be a bit overeager to do that).
