If you go to Settings->Display Settings and switch "Render Preference" from Quality to Speed (or vice versa), does this have any impact on the problem? If not, can you please send the PDF to mike@zubersoft.com so I can test this? If that does fix the issue, please let me know what you had it set to originally. It may still be helpful to have the PDF unless you are seeing this issue with every PDF you've tested.
Thanks,
Mike
