IM not logging

All three of my daughters are set as a "Child" in the profile option.  They are using AOL Instant Messanger adn teh activity isn'y being saved.  I verified that the monitoring was turned on adn still no luck.. I have uninstaling and reinstalling the program to no avail.  I am using Windows Vista, IE 7 and have Symantec Ghost, Internet Security 2009 and System works.  Any idea what might be happening?
