It's gone now. At the bottom of the posts, there was several text options other than just reply. I don't remember exactly, but, maybe, "Reply as PM", "Save", and a couple others. Oh, those were the text versions of the icons. I had never seen the text before.
The left pane, with the list of threads, looked like the formatting was all messed up. Each thread was prefaced with "Start new thread" or something like that. I should've hit a Prt-Scr and sent it to you. Next time I will.
Maybe it was a browser problem at my end. The PC may have been overloaded and it was having problems keeping up with the browser formatting.
