I'm currently using Mathematica 9 on Windows 8, and my problem is that every time I create a plot, it looks fine when I put it into a PowerPoint or Word document on my computer, but when I try to convert the entire document to a pdf or send the document to someone else, each of the individual points on my plots gets distorted. I've tried both copying and pasting the plots directly, and saving the graphic from Mathematica as each of the different available file formats which can then be inserted into Word or PowerPoint, and nothing seems to fix this problem. Thanks!
