title: Extjs masking and unmasking in IE and FF
body: <p>I have a handler, more like a submit button. And I would like to mask the whole page or that form to show wait message until the rest of the process is completed. I did this and it worked in FF but no success in IE, when I do <code>Ext.getCmp('').body.mask('Loading');</code> it does nothing, but when I add <code>.delay(1000)</code> it shows both in FF and IE and never ends the loading message...</p>
