Hi Rob: 

Thanks for this Rob.  I was coming round to the idea that they probably
weren't malicious.  They say a little knowledge is dangerous and
watching the packets and connections using Interarchy is a bit off-
putting if you don't know what's going on.

Happy Christmas/Happy holidays to you all.

regards,

Chris
