Execute this in firebug...

Code:



Ext.create('Ext.window.Window', {title:'AutoShow', hidden: false, modal: true, html:'This is an autoshowing window.'});

I would expect the window to show. It does not show for Ext 4.2 either.

It does show for Ext 3.4



Code:



new Ext.Window({title:'AutoShow', hidden: false, modal: true, html:'This is an autoshowing window.'});

I think this was mentioned in another post and I agree, I believe this default should be false.
