Thank you, Robynne. I did try refreshing, but it didn't work. I guess you're right - I'd better start typing it out first on word pad or some such. I just don't get it, though; I had finished writing the post, and when I clicked on 'Post', nothing happened. The rough copy didn't disappear, it was right there, but it just wouldn't post. When I clicked on 'Post' again I got a pop-up message saying that I had already clicked 'Post', and maybe I should try refreshing. Well, as I said, that didn't work. Nothing worked; no matter what I did, the rough copy remained, but it would not post to the thread. This is quite bizarre. I hope it was just a one-time glitch; if it happens again, that'll be the end of me trying to post on this forum. Maybe that's the idea.
