STILL BROKEN IN FIREFOX.

If I type some text in the window and try to change the order of words by dragging, I get what you see in the screenshot, so I can't see where I'm trying to place it. Dragging seems to have no effect anyway, and moving text by cutting and pasting doesn't work either.

It is also possible, while culling some of the quoted text, to get the cursor stuck inside the quoted text, with no way to get it out to the open space below to begin typing your own message.
