Forcing RealVNC v4 to only serve part of a multi head system?

[Sean J. Schluntz]

I have a Win2k desktop with two monitors (on two different video cards) 
which is unable to run RealVNC v3.3.7 reliably (it will work for a bit, 
but has the tendency to die when I try to connect to it - quite 
possibly because of the different video drivers).  When v3.3.7 is 
working it only exports the primary monitor, which is fine with me as 
the secondary monitor is mostly for VNC sessions.

I upgraded the system to the version 4 beta, and all of my crashing 
problems went away.  The system has been running w/o problem for the 
last week with me having made 50+ connections to it over that time.  
The problem is that it is now exporting both of my displays as one 
large 2048x768 window.

Is there any way to force v4 to only export the primary display similar 
to the way v3 did it?

Thanks!
