After upgrading several systems from Leopard to Snow Leopard there are now multiple instances of several applications listed in the System Preferences > Parental Controls > Allowed Apps
The applications may be duplicated 2 or 3 times in the list.
Why are there multiples in the list ?
Creating a new account on said systems does not reveal copies of apps in the Parental Controls list.
Does anyone know how to refresh the list of applications in Parental Controls for an existing account ?
