Define a master document that includes several files. Make sure you specify at least one of the parts with an absolute path. Now move the files somewhere else and open the moved master document.
You'll get warnings about not being able to find the subparts of the document that had absolute paths. However if you open the Documents menu entry you will find all those files listed. Now, what do you think might happen if you select one of those nonexistent documents from the Documents menu? If I can find time I'll look into this but don't hold your breath waiting. Allan. (ARRae)
