Интересно получается =)

stageHeight property

stageHeight:int [read-write]

Language Version : ActionScript 3.0
Player Version : Flash Player 9

The current height, in pixels, of the Stage.

When the value of the Stage.scaleMode property is set to StageScaleMode.NO_SCALE, the stageHeight property represents the height of the Flash Player window. When the value of Stage.scaleMode is not set to StageScaleMode.NO_SCALE, stageHeight represents the height of the SWF file. This property cannot be set.

По существу. Обратите внимание на Stage.align и Stage.scaleMode.
