This is an Easy problem. I just misunderstood what it was.. so basically 
this isn't my code causing the probem, but a flaw in the close code. When 
close is set to caHide, it simply calls to Hide, which means that the 
ShowModal code is never finished.. What should happen is if Hide is called 
when in modal if the form is closed the modal result is set mrcanel, (I 
think its mrCancel anyway) which cause the Showmodal to finish as though you 
had clicked a cancel button, and everything works a-ok.. all we have to do 
is in hide(or close), if fsModal in FormState then ModalResult := mrCancel;
