Sometimes if I open DU in a new window, without closing the old window, and go to the comment that I was posting on, then open a new comment or reply window, it will already be filled out with my old comment. It is frustrating, Good Luck!

clicking Post. This is when I too many times have encountered errors and the browser's back arrow button wouldn't bring it back, nor anything I can think of, and all was lost.

For a long time I've been in the habit of doing a Select All (Control A) and then Control C to copy to the clipboard before doing Preview or Post, and that's saved me numerous times. If it's an especially time-consuming post, I may also paste into a Notepad or Word file occasionally as protection from a computer glitch that loses the clipboard (and then sometimes I continue my editing there instead of in DU).

But during a DU spellcheck? Awk, what I do is only partial protection -- if I happened to save an earlier copy that wasn't too old.

Good luck
