Whats wrong with these f… forums now? When responding I loose all my text I've been righting just by hitting the backspace or changing the text.

You're using Chrome, yes? It does it to me, too. However, it doesn't seem to occur until after you've used the Enter button. If you keep it to a single paragraph there's no problem. I usually just type it all out and then go back an insert the paragraph breaks where appropriate. Or delete by highlighting what I want to change and then using backspace. Either way works, though I find the former to be the least obnoxious solution for me personally.
