Changing password for NIS 2010 in "settings"

Well, I figured when I set a password to access NIS 2010 settings (just trying to make it extra secure,) I figured if I wanted to change the password, I would hit "configure."  No such luck -- the NIS software doesn't even tell you that you CAN'T do it without reinstalling the SW!  I've never seen this kind of behavior before.  Anyone else run into this?  I could put it in the "suggestion box" for improvements/changes but I guess Symantec must have a reason for this.
