Abstract: A system and method are provided for determining the status of an application and altering the corresponding application window if necessary in order to convey information to the user and improve the user experience. The system and method of the invention allow visual treatment to be applied to a last active state of an application. The system and method further detect hidden dialogs that are shown in response to an application closing or exit request. The system and method additionally trap applications that respond to messages but ignore close commands and detect applications that do not provide visual feedback in response to user requests to close. Through these functions, a user is able to more readily distinguish between a non-responsive application and an improperly functioning application window.
