Hello, I need help from you and it would be really nice if someone could help me. I need to edit one book, I need to fix the margins and all that stuff. I am getting the files as Word documents and when I open the document in Word and when I started editing, the text just moved and it's all messed up. Can someone suggest any program or any way that I can edit already written book without the text moving?
Thank you, I would really appreciate your help.
