There are black lines and boxes in the eBook

This is a known issue with the default PDF viewer in Mac OS 10 and the PDFs created with Microsoft Word (which I use to create my PDFs). The way to resolve this is actually quite simple:

(1) Make sure your Adobe Reader version is updated. You can download it for free at

(2) After you download the PDF, open Adobe Reader first. Then from within Adobe Reader, open the PDF file.
