Links from one PDF file to another do not work unless you are using Adobe Reader (or Adobe Acrobat) to view PDF files from your web browser. If you have Adobe Reader installed on your machine, you control how PDF files are displayed from your web browser using a preference in Adobe Reader.
On Macintosh, run Adobe Reader and choose Preferences from the Adobe Reader menu. Click Internet in the Categories list and then check the 'Display PDF in Browser Using' checkbox.
On Windows, run Adobe Reader and choose Preferences from the Edit menu. Click Internet in the Categories list and then check the 'Display PDF in Browser' checkbox.
This issue with links is a web issue only - it does not affect the version of the PDF manual that is included with Igor Pro.
