wp-admin page opened in thickbox window not in parent window after login submit

hi,
i was using login form of page wp-login.php.
i have added thickbox and jquery in this page.My header.php calls this login form.
login form appears good in thick box window once lcick on login button , it shows forgot password ,Wrong password error message and go to back links are working correct.

I want when user clicks on login button with correct credential then it should appear on parent page not in self thickbox page.

Any help?
