BUT if I clear that option before clicking "OK", I then got an error message,
but still no capture window and hence no capture.
Error as follows -
"The capture session could not be initiated (Error opening adapter:The system cannot find the file specified ).
Please check that you have the proper interface specified...."
Notably "Link-layer header type:" option is blank and disabled in the
"Capture Options" window. (normally reads Ethernet)

Yes on Windows 98SE with WinPcap_3_0.exe and Ethereal 0.10.0
capturing Dial-up (PPP) works perfectly - (I use an internal winmodem -
Diamond supraSST pro DF). (I did have some minor problems when
using Sygate firewall - no problems with ZA or Kerio 2.1)
(Since I last formatted & installed Windows 98SE I've only ever had
WinPcap 3.0 installed - I've also just downloaded winpcap_3_0.exe
from the link supplied on ethereal's download page & did a FC /b
against my previous install file to confirm it is identical)
I read PPP support was removed from WinPcap 3 because of
problems with the way XP & 2000 worked, but I tried it anyway
because it didn't mention 98SE and was pleasantly surprised-
It seems it hasn't been removed for 98SE!! - I might add that it
fixed a problem with the packet times which used to be incorrect
using WinPcap 2.3.

When I uninstalled 0.10.1, and installed 0.10.0, I didn't bother to
uninstall WinPcap 3.0 and yes I could capture on both LAN
and PPP.
Ethereal 0.10.1 wouldn't capture at all, but it only gives
an error if I deselect "update packets in real time".
With it selected, clicking OK just makes the "Capture Options"
Window disappear and nothing more.
Hope that helps
