Graphical Update Slowdown when being Monitored

We have VNC Enterprise 4.1.3 server installed as a service on some
client Win XP Pro SP2 PCs. We use VNCViewer from the supervisor PC to
"look at" active screens. We have noticed that when a PC is being
viewed, the graphical updates on the viewed PC are slowed down to a
point where :-
1) The user notices it.
2) It interferes with the normal smooth operation of all programs that
update the screen.
We have even tried a simple text document in Notepad, and scrolling up
and down is smooth when not being monitored, and jerky when being
monitored. Any ideas, anyone?
