/**

 * be permitted to continue (many ignore the red error bar and keep
 * working, in vain). So now when this happens, we put up this
 * modal dialog box which cannot be dismissed. Instead it presents
 * just one option, a "Reload" button which reloads the browser.
 * This should trigger a re-authentication (or in the case of an
 * App Inventor upgrade trigging the problem, the loading of newer
 * code).
