I promise you that you won't do this more than 10 or 12 times, before you remember to quickly select text and copy it before hitting "submit"

The same thing frequently happens on Yahoo mail - hit "send" and it goes to a blank page. Grrrr. So I have no comfort to offer other than Blairvanhorn's good suggestion to use a word processor first. Tho I find that cumbersome for relatively small posts, I do recommend it for longer posts..

Sorry
