Hi Mat.

I'm running Win2k SP2 and Ethereal 0.8.18.  I installed
the MS Loopback Adapter then ran ipconfig to ensure that
the adapter had been assigned an IP address.  I then 
accessed the IIS webserver running locally on this machine
using both the Loopback Adapter IP and my NIC IP. I then 
started a capture session and selected the Loopback adapter 
in the "interface" field, but no HTTP traffic between my 
webserver and browser was captured. I then selected my 
NIC in the "interface" field and saw the same results 
(no traffic captured).

Maybe this problem is Windows specific?
