Why won't related documents open when I click their hyperlinks online?

This is most likely because the linked document has a character in its name that the PDF viewer or web browser cannot handle.  The following is a list of these "illegal" characters:

~  !  #  $  %  ^  &  (  )  =  +  {  }  [  ]  ;  '  ,

To resolve this issue:

1. remove any applicable related documents from the session
2. remove associated Link Document hyperlinks from the agenda
3. via Windows File Explorer - rename the files in their original locations
4. re-import the renamed related documents
5. recreate the Link Document hyperlinks in the agenda
6. publish
