                1. Use 'Modal' checkbox to select which dialog you're
                   going to create - modal or non-modal.
                   (this checkbox affects only new created dialog but
                   not existing one)
                2. Use 'Create Dialog' button to create a dialog.
                   If you have selected 'Modal' checkbox then dialog has to
                   be created modal - you can make sure of that clicking
                   on any other control (i.e. 'Modal' checkbox) - they
                   should not work.
                3. Use 'Show Last Dialog' button to bring up last
                   created dialog - to make sure that if you show/hide
                   modal dialog several times it stays modal.
                4. On the appearing dialog there are two buttons:
                   'Close Me' which closes the dialog,
                   and 'Create Modal Dialog' which creates one more
                   MODAL dialog just to make sure that
                   in situation with two modal dialogs all is fine.
                5. If created modal dialogs are really modal
                   (which means that they blocks the calling app)
                   then test is PASSED, otherwise it's FAILED."
