1.  The device popup menus on the control and mixer windows are linked
such that changing one will change the other to the same device.  It's
not possible to support more than one device at a time on the Euphonix
control surface.

2.  The alert for the Duet phantom power check when switching among the 
"Input" popup menu selections for the mic pres is suppressed.  If this
alert would have normally been displayed, and the phantom power is on, 
the phantom power will be automatically turned off.

3.  The alert for the overlapping existing output routing connections
when switching the aux channel output popup menu is suppressed.  If 
this alert would normally have been displayed, the existing 
connections are automatically removed.
