>Say a Form A calls a Form B and passes to the form B the value of itself (THISFORM). In the INIT method of Form B the value of the passed THISFORM (or Form A) is assigned to the form property FormB_ReferenceFormA. So now the Form B property FormB_ReferenceFormA hold the value referencing the form A.

Only if all the other references holding a pointer to Form A have been assigned something else or released.
