...is a web application which was downloaded from the internet. are you sure you want to open it? IF I WASN'T SURE, THEN I WOULDN'T HAVE CLICKED TO OPEN IT!!! How do I kill this annoyance?!?! People make fun of vista for stuff like this. What were they thinking bringing it to leopard? At least on vista I was able to find a way to disable it in a few seconds. I've been all over the control panel with no luck.
