[Winpcap-users] Lost packets on load

[Loris Degioanni]

This is very weird.
Are you using wpcap.dll or packet.dll? Did you start from the examples 
in the developer's pack? If yes, do they have the same problem? Unless 
there's some macroscopic bug that we never spotted, your application 
should not interact at all with other processes using winpcap.
