FileSystemWatcher getting Word temp file

[zfeld]

My app is creating a word document which my app calls saveas() and saves it
to a given directory that is being watched by a fileSystemWatcher. The
problem is that the fileSystemEventHandler for creation is only called for
the temporary filed created by word which shows up as ~$documentName.doc the
real file named MyDocument.doc will never invoke the fileSystemEventHandler
for creation. Now when the user closes Word the temporary file is deleted
and my app only had a handle to that file.
How come I am not getting any notification about the creation of the real
file even though it was saved using saveas() and I do see it created in
windows explorer?
