Text Box keeps copying from one box to other.
Hello,
I am using a document that has text boxes in 4 quadrants. When I am typing text in one box, and when I move to the next box, it copies the 1st box's text to the other ones. I erase the text in the rest of the boxes and it deletes everything I just typed. Can anyone explain why this happens and how to fix it? I literally cannot use this document with it like that.
