ZoneAlarm Lock kicks in when using VNC

AFAIK ZA does not watch for keyboard / mouse activity.  It
looks for internet activity, but from the symptoms, 'activity'
means a new connection (every http request is a new connection)
and my guess is that VNC starts a single connection, and holds
it open.  ZA does not see the traffic, just the make / break of
the connection, and thinks nothing is happening.
