Public Property OwnerSensibleMask As Long  | 
This is an unsafe method of setting this property, and is supported only for backward compatibility.
Use the CustomizationPermissions Object, instead.
Owner Sensibility is the  property of a field that determines whether the field can be modified  by its owner .
OwnerSensibleMask controls for which groups Owner Sensibility is applies.  A user belonging to a group with Owner Sensibility turned on can only change the field if that  user owns the entity.
The owner of a field is the owner of the entity to which the field belongs. Each entity type has it's own rule defining the entity owner. For example, by default a Bug's owner is the user whose name appears in  the 'Assigned To' field.
It's possible to change the owner definition by changing TB_OWNER_FIELD_NAME for the corresponding entry in the TABLES table.
