Internet explorer 9

I am geting this problem in the jscrip in ie 9.

initialize: function() {

GraphicsMill.BaseViewer.callBaseMethod(this, 'initialize');

//if (t.get_isPartialLoad()) return;

this._window = window.frames[this.get_element().id];

//WORKAROUND for Firefox

//After UpdatePanel refresh this._window.document equals null

if (!this._window.document) {

this._window = window.open("", this.get_element().id);

this._window.document.open();

this._window.document.close();

}

this._doc = this._window.document;

this._doc.clear();

this._doc.write(this._render());

this._doc.close();

the line this.doc.clear give an exception.

Can you guys look into it?

Thanks

is not supported by the ie9 browser that is the only error I get. I am using the latest version of gm.
