CK Editor 4.3 Instance Hang on IE

[HinaSynergyIt]

Steps to reproduce

I am using CK Editor 4.5.8 I am using Knockout js binding in my code We are using IE but it works on some machine but doesn't work on some machine

model dialog have 2 buttons Save and close

on model dialog initialization

<script type="text/javascript">

$(document).ready(function() {

ckInstance = CKEDITOR.replace("txtAnmeldelse", {

toolbar: 'Basic', uiColor: '#9AB8F3', resize_enabled: false

});

}); ko.applyBindings(new WorkViewModel(),

</script>

on close: call self.closeAndRefresh

self.closeAndRefresh = function () {

var instance = CKEDITOR.instances.txtAnmeldelse var editor; if (instance) {

first distroy and create new instance.destroy(true);

} window.close();

};

On page Edit mode call function : self.getWorkText

self.getWorkText = function() { var instance = CKEDITOR.instances.txtAnmeldelse;

var editor; if (instance) {

first distroy and create new instance.destroy(true);

} ckInstance = CKEDITOR.replace("txtAnmeldelse", {

toolbar: 'Basic', uiColor: '#9AB8F3', resize_enabled: false

});

ckInstance.on('instanceReady', function (e) {

editor = e.editor; window.setTimeout(function () {

solution for permsion denied issue Permission denied when calling setData very fast ​https://dev.ckeditor.com/ticket/10501

e.editor.setData(self.WorkText().Anmeldelse, {

callback: function () {

this.checkDirty(); true - to clear previous intance

}

});

}, 50);

});

}

Expected result

First time it load correctly but when i close pop-up window and reopen it i hangs.

ck Editor and give error permission denied on get_attribute function and make IE and CK editor responsiveness

Actual result

CKEditor should be open and bind correctly and should be destroy correctly
