            parentless, according to the corresponding button's test.

            Press each button one after another. Make sure that all
            parentless dialogs have an icon in the windows taskbar
            and all the dialogs with parents don't. Press PASS or
            FAIL button depending on the result.

            Note: as all the dialogs shown are modal, you have to close
            them before showing the next dialog or PASS or FAIL buttons."
