This quite possibly doesn't happen often enough to make it worth addressing, but I was typing a response to someone today and when I went to submit the reply, I was told I couldn't post in a read-only area. It appears that a Mod locked the thread and moved it to a different area while I was typing my response. This means that my response was lost, and if I still want to help the OP, I have to type the whole thing again. Perhaps I should compose things in a separate Word document and then paste when ready to post. Anyway, not a huge deal, but I don't really feel like retyping the post, yet I do want to help people with their questions.

Can't tell you how many times this has happened to me, too! 
And frequently, my would-be reply starts out with something like, This post would do better on such-and-such board.
Every now and then, I think to copy the post before hitting the button. (Too lazy to paste it into Word; it just stays on the Clipboard, I guess.) If the original gets moved, I can then slap the reply on the new location. But it's certainly not something I do automaticly, mainly because I rarely remember until it's too late.
