Allow a user of a form to add a hyperlink to a file on a network.

[HeleneJ]

I've created a form with a rich text field. I would like users to be able to
add a hyperlink to various pdf documents of their choice that are located on
our network drive. InfoPath automatically adds "http" to the front of any
path the user types as the hyperlink. Since they're not linking to a Web
server, the hyperlink doesn't work. Is there any way to simply add a link to
a document like we do in Word or Outlook without having InfoPath add the
"http" prefix? Thanks for any help!
