Can't get to display screen

[Jana Nguyen]

Hi there,

After entering the ip address of the vnc server and password on the vnc 
client to connect. This authenticate fine, but it gives me a blank grey 
screen with only 2 radio button after authentication:

1) Send clipboard to viewer
2) Send primary selection to viewers

I am running the vnc server Xnvcn version 4.0b4 on Red hat linux 
enterprise 3 workstation, and vnc client 4.1.1 (free edition)  on 
windows xp.  May I ask why am I getting the problem above and how to 
solve it?

Thank you,
Jana
