It is possible that while you were setting things up that you opened a hole
in the firewall that allows vnc in.  You can and should lock vnc to only being
available on the hamachi network connection, by going into firewall advanced,
selecting hamachi and add vnc tcp 5900.  After that go into exceptions and
turn off vnc.  This should block vnc from accessing the computer except through
hamachi.  Now if someone is connected to your hamachi network then they should
show up in you status program for that network.
