I'm sorry this post is so old, but I've done everything suggested and I still don't understand.
Mostly because the justify option isn't greyed out on my screen, it literally is not there.
I have been typing into a text box, so it is a paragraph, not "point" style. I've just been typing, not adding my own line breaks.
What do I need to do??
EDIT: open word, write stuff, justify it, copy and paste as image. k thnx.
