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.
