Answer 1

The Method show() (toFront() also) will do the trick for you. Here a small example:

var a = new Ext.Window({
    title: 'a', 
    width: 200,
    height: 200
}).show();

var b = new Ext.Window({
    title: 'b', 
    width: 200,
    height: 200
}).show();

a.show(); // or a.toFront();

There is also a property toFrontOnShow, but it is true by default.
