                is the number of screens on your system. If X is incorrect, press Fail.

                In the test window, there are a list of buttons representing each
                type of dialog for each screen.
                If there aren't buttons for every screen in your system, press Fail.

                Press each button, and the indicated type of dialog should appear
                on the indicated screen.
                Modal dialogs should not allow to click on the Instructions or
                DialogTest windows.

                The buttons turn yellow once they have been pressed, to keep track
                of test progress.

                If all Dialogs appear correctly, press Pass.
