Ctrl+Alt+Tab with Xvnc

[Susanta Kumar Padhi]

James,

Actually, I Developed a light weight desktop and plugged  in in the
gnome session so that when GDM starts my desktop.As I am starting Xvnc
through xinetd as soon as a connection comes it call the GDM so user
gets my desktop. In the physical system itself it does not do any thing
if I press Ctr+Alt+Tab. I am not giving any terminal to the user, they
have only some icons for through which they r accessing customized
applications so they can't type any command. But I don't know how it
happens in Java vnc viewer.

I tested with windows vnc-viewer it does not send any control keys such
as Ctrl+Alt+Back space or Ctrl+Alt+Tab any thing. But why
java-vnc-viewer does this. 

The Ctrl+Alt+Backspace, F1... All are Xserver hot keys. That means
Xserver Getting these through java-viewer

Kindly suggest if I am doing any wrong.

Regards
Susant
