I posted a reply to a similar question on comp.windows.x:


	There are a number of bugs with the xnews server in OpenWindows 2.0
	including one that might be causing the problem you are encountering.
	When a button is grabbed (i.e, betwen button press and button release)
	some events get discarded.  We noticed that LeaveNotify events get
	discarded when a button is grabbed (this breaks Motif toggle-button
	widgets when using the default translations).  We have not received a
	fix for this server bug yet, but Sun is aware of it.
