Syslinux - May 2005 - Isolinux freezes loading configuration file - fixed in 3.08-pre11.

Follow up,

While awaiting my initial message to clear the moderator, as my
company's Exchange server tacked on some bogus header, I downloaded
version 3.08-pre11 (vs the 3.07 I was using).  This newer version seems
to work correctly.
