[CentOS] vncviewer package wit hcentos 5

I have xkeybindings running just fine on centos 5.
I have vncviewer running in full screen mode showing another PC.

When vncviewer is running is running it seems to override my xkeybindings.

Is there a way to tell vncviewer to not bind to any keys?? The only keys 
I am binding
is on the Keypad 3,4,6, 9 and Enter. Nothing that vncviewer uses anyway.

How can I still have my xkeybindings active with vncviewer running?

Thanks,

Jerry
