What I did find though was that 98 was best using WinPcap
3.0, and 2K & XP worked better with 3.1 beta 3. However, it will
probably be best seeing which works best when Ethereal 0.10.7 is
properly released.
The chances that Ethereal 0.10.7 will make any difference whatsoever as
to which versions of WinPcap work better with which versions of Windows
are very slim, because that's a WinPcap issue. Ethereal just uses
libpcap/WinPcap and relies on it (libpcap/WinPcap) to handle the details
of packet capture on a particular OS.
If you're having problems with particular versions of WinPcap and
particular versions of Windows, you should try to reproduce them with
WinPcap (to make sure there are no Ethereal issues) and then report them
to the WinPcap developers.
