Never saw this one before. All of a sudden this afternoon I am getting repeated pop-ups on IE 11, Win 8.1 "are you sure you want to leave this page?" when clicking to any different thread. It wasn't doing this this morning on this same machine, and no settings were changed here. Also- I can't post images. No matter the source or host, and my own web server, makes no difference, just see the one single HTML tag and that's it. Anyone else seeing this?
