Thank you for posting. Besides numerous unit tests, Aspose.Words also contains many regression tests, including the PDF export area, so the probability of regression is pretty low. I've tested your document on 3.7.1 and 4.0.0. Maybe I missed something but I haven't noticed any obvious worsening. It is strange but the document produced by AW 3.7.1 here differs from that posted by Kevin. Anyway, I have logged this issue as #1281 to double check. If we find that Aspose.Words actually caused some of the issues, we will fix them and notify you here immediately.
