Login Items

System Preferences>System>Accounts>Login Items

I learned that you can control what programs automatically load right after you login by going to your account and altering "Login Items".  There is a list of programs that will start automatically.  You can click on any program you don't want to run automatically (during the start up) and click the minus (-) under the selection box.  You can also click the plus sign (+) to add a program you would like to run automatically.
