Hi WillElearn,Do you know the origin of these documents? How they were
made and/or anything else about them?When you go into Edit, are you able
to select these lines? What I have a hunch is that the lines are not "in
addition" to the normal thin lines you are expecting so that if you were
to delete them, there would no no line. Nonetheless, you can try and and
hopefully my concern may not be correct.One other option is if you have
Adobe Illustrator, you can open these documents into Illustrator,...
