Just throught I'd mention it, in case anyone else having the same problem was wondering if it is just them.
Sometimes when I select and delete a portion of a quoted message in my composition window in Mail-News, I get a blank space where other text is lost. Scrolling up and down doesn't refresh the window -- I have to minimize the window, then restore it, and this returns the mysteriously vanished text, and I can finish writing my post and send it off with no other problem.
