Norton Safety Minder - OnlineFamily.Norton

I have the controls set to log out my child when she exceeds her time limit on the computer.  When that time is reached she is shutdown from the internet and the desktop clears all icons and the dock and then the computer freezes.  In other words it is not going through a true log-out for that user.  There is no way to sign out or do anything on the computer when this happens unless we do a "hard" shutdown of the computer and restart it.  I had assumed that when the controls were set to logout that would log-out the child from their internet session but allow all other computer functionality.  Is this a bug in the program?
