Dragging Window causes window to hang ("Grey out")

[danielleng]

When I drag an Ext.window.Window it sometimes freezes/hangs and I can't close or minimize it anymore. It just grays out. Anyone experienced this before ?

Here's my declaration... nothing fancy. Just simple stuff:

Ext.define('Portal.view.user.form1' ,{
extend: 'Ext.window.Window',
alias : 'widget.form1',

title : 'Input Details',

layout: "fit",
height: 200,
width: 300,

autoShow: true,
resizable: true,
minimizable: true,
closable: false,

initComponent: function(){
this.items = this.buildItems();
this.buttons = this.buildButtons();
this.callParent(arguments);
},
......other functions......

What version of Ext JS 4 are you using?

[danielleng]

I'm on ExtJs 4.0.7.
Update: It hangs most often when I attempt to drag it around during the first 10 seconds or so of my app finishing loading all the components and panels.. Could it be that it "has not completely loaded" yet and so dragging it around would cause it to stop working ?

No, once it is visible, it's good to go. I have not seen this behavior at all.
