take a look at any when-window-closed trigger in the form

If any part of the application is in an "Enter-Query" mode you will not be able to exit until that mode has been released. So, if you execute EXIT_FORM while in this mode, the result will only be that Enter-Query mode is terminated. You would need to execute EXIT_FORM again to exit the form completely. So, in a WHEN-WINDOW-CLOSED trigger, try this code:
-- This supresses the Enter-Query mode cancelled dialog :System.Message_Level := '10'; -- This cancels Enter-Query mode exit_form; -- This exits the form exit_form;
