+	<p>
+	This is a useful kind of framed window that uses 
+	the property set to get window size and position
+	and colours. It can also send window closing events
+	to the default command handler (see Agency) as
+	"exit" actions.
+
+	<p>
+	Addition: frame can dispose of itself when last component
+	is removed.
