Ext version tested:
  • ExtJS
  • Sencha Cmd

Browser versions tested against:
  • Windows 8.1
  • IE11

I create a function that close all tab windows when log off.
But when I try to get the tab window's name from my application, the tab window which made by Ext-Js returns the empty character string, so I can not close the tab window.
This problem happens only Windows 8.1. the Other OS are fine.

I guess this function is the issue.

microloader.js (line 2251~2259)
     * @private
    notify: function () {
        var listener;
        while((listener = _listeners.shift())) {

  • what is this function used for?
  • can I comment it out?
