Hi,

I'm facing an issue in using iframe (Version: Extjs4.1.1) that when iframe contains large content, application hangs on IE9. (In my case, iframe contains a document of 10.4MB ). It is super heavy on IE9, it even crashed IE once for me.



Ext.define('Int.IFramePanel', {
extend: 'Ext.panel.Panel',
initComponent: function () {
var me = this;
me.callParent();
me.mon(me, 'afterrender', me.afterRenderHandeler, me);
},

afterRenderHandeler: function (ct, position) {
var me = this;
me.frame = me.body.createChild({
tag: 'iframe',
frameborder: "no",
border: "0",
style: 'width: 100%; height: 99%',
src: me.url //contains source url of my document
});
}
});


Is this the problem of IE or is there issue in using in EXTJS? Please suggest any solution in both case.

Ext doesn't do anything extra with frames. When you've got Ext loaded, there's more memory being used, but other than that, there's no special handling.
