Hypertext links in Acrobat 8 documents generated from FrameMaker 8

[Austin Meredith]

I've recently upgraded to FM8 and Acrobat8 and now the new links in 
the Acrobat documents I am generating won't function.

I suspect I must have had some option set in my old Acrobat7 that I 
have forgotten to set in my new Acrobat8, because the links I used to 
generate still function. However, ADVANCED > DOCUMENT PROCESSING > 
CREATE LINKS FROM URLS doesn't activate my new links. -- What toggle 
have I forgotten about?
