I use many references in my documents to other files on
our network.  However I noticed that the hyperlink
addresses get modified under certain conditions.

A typical hyperlink I use would look like:
file:///\\\engineering\project\products\my
product\specs.doc

However, a few days later I re-open my document and the
hyperlink has been changed to file:///G:\products\my
product\specs.doc

This is most likely the result of my document being loaded
by some other user who has \\engineering\project mapped to
his G: drive.

How can I prevent this from happening?  Different people
in our organization use different drive mapping, and this
changing of the hyperlinks renders them useless.
