If the form is created from another object (form, application, etc) then there may be a lingering reference to it there. Not sure why the Hide() would solve the problem though.

>>>Hello,
>>> I am having a problem closing a CHILD FORM in an application. There is no error in the form and everything works normally but when the user tries to close the form nothing happens. The CHILD FORM is not MODAL.
>>>The code in the EXIT button is THISFORM.RELEASE
>>>
>>> This behaviour is only during RUNTIME. Is there any way to find out the problem or FORCE to close the CHILD FORM from within the MAIN APP.
