[OS X TeX] \includegraphics and Annotated PDFs

[Rick Zaccone]

I have a PDF file that I created by taking a screenshot of an  
application.  I opened the PDF in Preview and annotated it with an  
oval to highlight a button in the screenshot.  Then I saved the file.

When I use \includegraphics to display this PDF, it displays without  
the annotation!  If I open the file in Preview, it shows the annotation.

I tried annotating the file with Skim and got the same results.

I am using

\usepackage{graphicx}

I've done this before and it worked.  Could it be Leopard?  I'm using  
10.5.1 and TeXShop.  Does anyone know why this isn't working?
