[Chris McDonough]

Update of /cvs-repository/Products/ExternalEditor/Plugins
In directory cvs.zope.org:/tmp/cvs-serv28211

Modified Files:
	winword.py 
Log Message:
If the user modified an open document, but never actively saved his outstanding changes, and instead relied on the "do you want me to save?" dialog that Word presents when choosing to exit the program, the changes would never be saved and EE would exit without an error.
