this is one of those problems that are a pain to debug...

First of all, does the problem appear with the latest WinPcap beta version 
as well (4.1 beta4)?
If yes, a solution to this is force your laptop to crash and generate the 
crash dump. There is a way to crash the machine through the keyboard. If the 
problem happens on beta4 as well, I will tell you how to do that.

Have a nice day
