Trouble with PowerPoint

I have been having difficulty with printing PowerPoint presentations to .pdf.

When I save the pdf name, I get a small box saying that PDF Creator 0.9.9 (Not Respondng)  Sometimes the file goes through and sometimes it just locks up.  When it does go through, it seems to expand the file:  A 1Mb PowerPoint presentation becomes a 9Mb pdf. 

Seems like it should go the other way.
