Your best bet is to use Word's events. If your VFP app will be running when they modify the document, go with the solution Cetin outlined. If there's a chance they'll close your app, but keep working in Word, you need to use a Word add-in to handle this. I wrote an article about what's involved. It was in FPA in 10/02. I also showed the code at DevTeach and DevCon last year.
