Have you received any helpful response, or otherwise resolved this issue? Mine is similar - I used to be able to convert from WordPerfect to pdf and all links would function. But since upgrading to Acrobat 9 & WP 5x, the links don't work (they look nice, just don't 'do' anything). Any light you may be able to shed would be appreciated!
Could you let me know which version of Adobe Reader 9 are you using? You can try updating to the latest version ie 9.4.2 by doing a Help > Check for Updates.
That should fix the issue.
Alternatively, you could even download Adobe Reader X from ftp://ftp.adobe.com/pub/adobe/reader/win/10.x/10.0.0/en_US/AdbeRdr1000_en_US.msi
Hope this helps.
Thanks Ankit. I've since learned that PDF/A documents do not permit links to outside sources, it's just the nature of the beast. Please correct me if wrong, but I think that's it and trying to get links to work in PDF/A documents is beating one's head against the wall, that dog will never hunt.
