Have Adobe Reader 9 installed and using Internet Explorer V. 7 on a PC. On a particular web site I can't open PDF files from their hyperlink -- just get a blank box. Have turned off all firewall, cleared history/cookies, etc. to no avail. The web site's technical support has no more ideas, as they are able to open the links from their end. Problem seems limited to a particular web site, as I'm able to correctly display on other sites. I am also able to open them using the Firefox browser, but not internet explorer. Any suggestions would be greatly appreciated!
To make the hyperlinks in PDF file work, do the following:
Open your Adobe Reader
Then select Edit à Preferences… from the Action Bar.
To make the links active, select Documents (under Categories). On the right side, now under PDF/A View Mode, using the drop-down change “Only for PDF/A documents” to “Never”. Now click the OK button.
