two monitors - one keyboard

[Tom]

Hi VNC experts,
I set up a vnc connection between a Solaris 10 x86 machine and a Windows PC.
I have two monitors, two keyboards, two mouses on my desk - each of them connected to one of the machines.
I just want to use one keyboard and one mouse (the Solaris ones) to access both systems.
On Windows VNC server is running and when I start vncviewer on Solaris I get an xterm back on the Solaris machine with my Windows session.
I don't want that really ... what I want is to have the mouse and keyboard working as I was sitting on just one machine (i.e. if I move the mouse to the boarder of one monitor I should see it on the second and vice versa and be able to work there).
I am using the vnc package from the Solaris companion CD and the RealVNC Server Free edition on Windows.
Thanks in advance for your help,
Tom
