the system cleans up after you, but still warns you about it and it is
good practice to resolve those memleaks since your app could run out of
dynamic memory during execution time. In your case you have to free the
old text handle which is associated with the field. otherwise it is
getting forgotten,thus the mem leak warnings. the new text handle,
associated with the field, will be freed when the form is getting
destructed.
