How do I edit my startup programs for Mac OS X?
In particular, I have this "Hotspot Shield" program I installed that is starting up every time I reboot my computer. I want to remove it from auto-startup.
Assuming that program is started upon login, not upon booting:
System Preferences » Accounts » Login Items shows the things started at login. In that screen, select the program and click the "minus" button to remove it.
