I have what on the face of it looks like a winpcap problem, except . . .

This makes NO sense to me, and probably everyone else,  but I'll throw

and it still works as always (and with the same list of devices) with

I went back to the previous Snort (I copied the directory before the new
install) and the problem is the same. I tried a 1.7 I have on the same
machine, same problem.

I am decidedly puzzled. (Mind you, today was one of those days. Maybe
tomorrow . . . )
