Thanks Bruno for your help.

 From your screenshots, it appears that your Acrobat rendering is  
better than my son's or what I get for windows. If you are willing to  
look, the pdf produced by XeLateX and TeXShop (with standard  
settings,"Regular") is here
A screenshot of what I get with the Latest Acrobat for windows with  
win XP SP2 under VMWare Fusion is here
 From what I have seen on the XeTeX site ( http://scripts.sil.org/cms/ 
scripts/page.php?site_id=nrsi&item_id=xetex_download )
XeTeX has not been updated since 2006, so I assume I have the latest  

Or maybe the pdf engine has changed for Leopard? I am under 10.4.11.
