you must manually erase the subject line before responding. It's not hard. There are two methods: 1. Place cursor all the way to the left, then hold down your "delete" button until all the words are gone. 2. Place your cursor all the way to the right, then hold down your "backspace" button until all the words are gone. Then type in what you want to say. You have to use the "tab" button on your computer to move to the "Message" area.
