Can't lock local keyboard when AllowProperties=0

Thanx for the input, William.
Unfortunately this didn't have any noticable effect.
Is it actually possible to prevent user access to the properties dialog, as well as lock the local 
keyboard when accessing the server ?  It seems odd to have two different security features that 
cancel each other out.
I am in a school situation, & am using VNC to monitor/control classroom PCs.  I want to be 
able to access a student's PC & kill any inappropriate activities (web browsing etc) without 
having to fight for control of the mouse.  I also don't want students to be able to fiddle with 
VNC properties, for obvious reasons.  Surely these should not be mutually exclusive aims ?
Any help appreciated.
