Thanks, I was able to get it to work with windows in a moment, but I can't make it work with ubuntu.
At first the real desktop popped a window, asking for permission, when given, vnc just disappeared, so at least it tries to connect. So I turned off the ''ask for permission'' option, and vnc simply dies when the connection is attempted.
My experience with linux is very limited, so I don't know whose fault it is, or even if it is supposed to work with gnome/ubuntu at all.
Anyway great work,
