Microsoft enhanced the implementation of standards mode and changed compliance in Internet Explorer (IE) versions 7 and 8.
Partially because of the tabbed interface, when you interrogate IE versions 7 and 8, Studio adds new objects to the hierarchy in Object Explorer between the window and Shell DocObject containing the browser. For IE7, one object is added. For IE8, two objects are added.
Captured objects display in the normal hierarchy below the extra controls. Use the objects as you normally would in Studio.
