I don't understand this.  `_dos_open' doesn't do anything
significantly different from `_open' (called by `fopen'), so why
should the effect be different?  Are you sure `_open' doesn't work
also?

One thing that I would suggest is trying to set the DENYNONE bit in
the access/sharing mode byte.  That might allow some access to the
file.  Of course, if Word opens the file so that nobody else can
access it, nothing will work.
