To rollback a property to its inherited value:
Note: The Inherit command on the Property Palette toolbar is the only way to convert a variant property to an inherited property. Simply setting a variant property to the same value as the property in the class does not create an inherited property; rather, it creates a variant property that happens to be set to the same value as the property in the class. If you subsequently updatethe property setting in the class, the property is still variant and so will not inherit the change.
