	This can be addresses with force create mask:  Word
	and friends edit files by first renaming the input
	file to .bak, and then creating a new output file
	and filling it with edited output.

	The creation tends to take permissions off (windows
	doesn't grok such), so you need to "force" them on.

	Case 1: the user is of the "right" group for sharing.
		Add "force create mask = 0660", which will
		or in the bits for rw-rw---- 
	Case 2: the user's primary group is foo, but you
		want the file's group to be bar.  Use
		the force create mask, and either use g+s on 
		the directory or "force group = bar" in the
		smb.conf.

	These options can be set on a share-by-share basis, so you
	can tune them a bit.

	Blush: I don't know.
