2nd Edition PHOENIX Memorial CDROM
A member reported that the links on the index page of the 2nd Edition PHOENIX Memorial CDROM did not work with Acrobat Reader v9. It turned out to be caused by the default value of a preference option. Here is how it was corrected:
Documents->View Documents in PDF/A mode: NEVER
From the Edit menu, select "Preferences", then choose to look under Category "Documents".
The option "View Documents in PDF/A mode" should be changed to "Never".
