Now when you click reply you will get a pop up window to type on..but it will have the same message showing that you were replying too...depending on which reply you clicked in which message..
but if you are like me you do NOT WANT THAT SHOWING AGAIN ON YOUR MESSAGE SO you need to go to the top of the pop up window and click the RICH TEX EDITOR
After you have done that then take your mouse and put across all the words and hightlight them then delete or cut them so you have a new blank area to put your message in.
