I have my firewall set to "allow specific services and applications." I noticed today that DashboardClient, System Preferences, and a program called "ScreenSaverEngine." Are all set to allow.. Typically i'd just want itunes so I can use simplify media, and safari/firefox because i think it has to be enabled. What are the parameters for allowing a program incoming access in general - i seem to get asked it now that I have this option checked and wanted to make sure? I find it odd that i have some system utilities on my list set to allow - is it just me?
