                When you see a frame titled "PopupMenuCrash Test", right-click on it
                several times for a few seconds. Then wait about 10 seconds before the
                PopupMenus start to appear. Then dispose them one by one by clicking on them.
                When PopupMenus do not appear anymore, press Pass.
