One thing that causes this is that the session expires while you are writing a long message. A symptom of that is going back to the main forum pages when you hit Submit. If that happens, usually the Back button will save you. But if you go back, you still have to Select All/Copy, then refresh. If you refresh first, your message will go away. If I feel long-winded (who, me?), I write in TextPad, then paste to the Body. M
