Are you sure about that? I don't have a title entered in constructor and
all seems to be well after I change the form's title. It doesn't seem to be
leaking memory. If I try to free the memory after I'm done with the form, I
get an error. So it would seem that the form is releasing the memory. But
is that true for all cases?

Thats not true for a field. If the field pointer is not NULL, the field
will release the memory even if you dynamically allocated it.
