Graphical Update Slowdown when being Monitored

[Mark Jacobs]

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?
