Norton Safety MInder Lets My Son Back Onto The Computer After His Time Limit Has Expired

Norton Safety MInder allows my 5 year old son to log back onto the computer after his time limit has expired. After logging back on, he will have approximately 2 minutes before Safety Minder logs him off again. When the log off occurs, he will log back on for the process to repeat itself. Why does this occur and, more importantly, what can be done to fix this up? Thanks in advance for any reply.
