Legibility of Documents in Captivate 8

I am new to Captivate and using 8.  In building my first slides I am using a document with text, boxes, etc.  They look fine when I see them on my screen as I build the slides, but when I "Review" them, the words and lines are fuzzy, the lines do not connect and pretty illegible.  Does this happen just during Review? Or, do I need to do something different to improve clarity?  Thank you.
