Igor:
Interesting. If you look at the network traffic, I
can see that the VNC detection *does* send the packets, and
there is an ACK response from the VNC server when these
packets hit the right port. This is why I thought it might
be a bug in the packet-receiving process, rather than the
packet-sending process.
