Overall this is an excellent App, except for one small thing: The 'Whois" map has never worked. It consistently displays a "cannot connect to server" notice. When one buys an App, one tends to expect all the features to work (especially at $29.00, or $79.00 for the full Security Suite of which this is a part). The developer hopes to have this problem fixed in a future update, but several months after pointing this out to them, it still does not work. It would certainly be nice to use all the features I paid for. Even once.

Excellent program. I've been using this for about a year and a half. First with Doorstop, now with Norton. Extremely useful. It's called "Who's There?"...not "Who Is There?".
