Expanded Stage Work Area

From the what’s new:
*You can use the area around the Stage to store graphics and other objects without having them appear on the Stage when you play the SWF file. Macromedia expanded this area, called the work area, to allow you to store more items there. Flash users often use the work area to store graphics they plan to animate on the Stage later, or to store objects that do not have a graphical representation during playback, such as data components.

*I simply could not make this work… Does anyone else have tried it?
