Then I have absolutely no idea why Ethereal can't open it (unless
WinPcap 2.3beta is somehow treating the device path argument in
"pcap_open_live()" as a Unicode string), especially given that others
have, apparently, successfully captured packets on Windows XP with
Ethereal.

I don't have Windows XP, and thus cannot explore this any further (and
don't have time to do so in any case).
