I can save 3-4 SolidWorks 2009/2010 drawings as a pdf and everything works perfectly. After that most, if not all, of the company logos, renderings, excel tables, etc start becoming black rectangles. I can save it as many times as I like, once it starts doing it and it keeps making black rectangles. If I restart, I can save 3-4 more drawings. Rinse & Repeat.

Anyone have any suggestions?? (Besides restarting every 3-4 drawings)

Attached is a drawing working fine, and a drawing that is having issues with life.
