Users of Mac OS X Snow Leopard may have noticed a new feature called Dock Expose. If you click and hold on an active icon in the Dock that will trigger Expose on just that one application, showing all the application’s active windows together with special options such as Quit and Hide.

The computer is running Windows XP SP3. (more…)
