I tried this question earlier but with no success. Trying again to see if any other experts have any ideas.
When I Hyperlink to external files from within a Powerpoint Presentation and then run the show from the viewer, I get a security alert when I click on a link. This happens for all file types, Word, PDF etc. My presentation has over 50 links so I get 50 messages. It is very annoying after the first few messages.
