Seems to work well. One fix is needed.

Just installed this and it works as promoted. Tested it and it gave a pop-up notification when a certain user logged in, one of a few that I had specified to be notified about.

One issue that should be fixed:

I checked the box to tell this program to launch automatically when I start up my computer.

However this program takes just a second to launch, BUT skype (which is also in my launch-automatically list) takes a long time to launch. So, what happened when I logged in? This contact-alerts program launched immediately and gave an error message "unable to connect to skype." Because skype had not launched yet.

therefore, every time I start up my computer, I have to launch this program manually after skype has finished launching.

I can imagine a short-term partial fix and a long-term real fix:
-- short term: please make it so that the error message alert does not simply have a "QUIT" button on it, but instead has a button that basically says "Try again now." That way the user can just wait 10 seconds until skype launches, and then click that button.
-- another short term fix -- simply have a preferences configuration option to tell this program to wait XXX seconds before truly running and trying to connect to skype. That would then make it launch correctly when the computer starts up.
-- long term fix -- have the thing intelligently figure out that skype is not "available" but however is trying to launch, and therefore have it wait 15 seconds and try again itself.

anyway -- good program with that one flaw.

thx
