You may password protect a program icon or individual entries within a 
group icon.  When creating an icon or adding a program to a group icon, you
are asked if you want to include any parameters or a password.  Click on YES.
Next, click on the PASSWORD button.  A box pops up for you to type in your 
password.  Be sure that you typed it correctly.  You may want to write it 
down somewhere in case you forget it.  

When you click on an icon or entry in a group icon that is password protected,
an input box immediately pops up.  To gain access to your program, you must 
correctly type in the password.  Note that when you type the password, each
letter is substituted with an '*'.  This keeps your password hidden from 
other people.
