I just installed the program and tried using it to 
grab the VNC site <http://www.uk.research.att.com/vnc/>

The default settings should ensure that the grabber 
only grabs things from /vnc/ and lower, but when I ran 
it, it started to grab things from / and from there 
grabbed EVERY SINGLE FILE on that webserver.

I even tried setting it to only download /vnc/ 
directory and nothing else, but it still insisted on 
grabbing all files on the server.
