Apologies for the delay in responding,as I needed to be at the console
of my office machine to check the key settings, but that isn't
subscribed to the list.

My setup at work uses twinview, with 
Screen 0 is 1280x1024
Screen 1 is 1600x1200

xdpyinfo reports the display dimension as 2880x1200 pixels

So TwinView takes the two monitors, and combines them into 1 extra-wide
display.  I presume, from what you describe, that you are using separate
X screens, rather than TwinView.  I haven't tried that setup.
