If I understand your question (trying not to assume I do), the form 
gets destroyed but the resource is not freed unless you delete the 
pointer to the form.  For example:

Form2 = new TForm2(Application);
Form2->ShowModal();
delete Form2;

In this case the Form2 gets destroyed when a button with a 
ModalResult is clicked or the form is explicitly closed with a 
Close() method.

You can test this by placing a call to a message box in the OnDestroy 
event of the dialog form.
