VNC Client/Server has different display

Hi,

I set-up my VNC Server on a Fedora 13 and I have a client on windows.
I can access the Fedora PC but when I move the mouse and click on folders, I do not see the Fedora Desktop updating (I don't see the things that I am doing in my client on the Fedora PC)

Then, when I do something on the Fedora PC, I do not see it on the client....

No problem with the control, I just want the image on Fedora PC to be the same as the one on my client and vice versa.

Anyone can help me with this?
Thanks!!!
