I am using 4.1 version.
I have selected "remove wallpaper when connect" box inside the server 
However, I still can see the wallpaper in the connection each time.  What 
is going wrong?

Moreover, it is about XP's switch user issue.  I open the VNC server in 
User_A account and i cant switch to and view User_B account.  The system 
brings me to the user selection screen.  Can it be solved?

Thanks everyone!!!
