I use the SEWDatalink script rather than ASEWS.
It persistently stores the Sector state so you get one message when khaak spawn and another when the sector has been cleared. No slew of messages when loading a saved game. Standard nav sats are supported too (I think with reduced scan radius).
It also comes with start/stop and uninstall scripts that worked without a hitch for me. (removed before patching to 1.3)
The only annoying thing is I dropped of Nav sats everywhere while exploring the galaxy so I log incursions all over split space even though I have no interests in the whole of their space. Still, I can just leave it and get no new messages until home forces clear the sector or the khaak kill my sat.
Very useful script when you only have limited sector defence. Defence forces can be jumped around where needed
