I know what you mean, Altered State, I have that happen all the time too, especially in my Webmail accounts. I do get so I copy the whole thing every so often if I know I'm going to go looking for things elsewhere or I put up a small WordPad or Notepad screen to play in while I get it right (or sometimes even post it and then edit the post knowing the "bulk" of it is safe). And I try to convince myself, when I do wipe it out, that it was "meant to be" and that I am glad I didn't post that particular post, that I was too wordy or something :-)
