Maximize() Restore() Custom Script

Hey, I have been trying to creator a custom window for an AIR for desktop App.

minimize and close is a breese but maximize and restore is a bit tricky.

I set my stage to NO_SCALE.

private function restoreWindow(e:MouseEvent):void

                    {

                              if (stage.nativeWindow.displayState != NativeWindowDisplayState.MAXIMIZED)

                              {

                                        stage.nativeWindow.maximize();

                                        restoreIcon_mc.gotoAndPlay(2);

                                        MovieClip(this.parent).stageBackground_mc.width = stage.stageWidth; //stage is 1280

                                        MovieClip(this.parent).stageBackground_mc.height = stage.stageHeight; //stage is 800

                                        this.x = stage.width * .95;

                                        this.y = 6;

                                        trace(stage.stageWidth, stage.stageHeight)

                              }

                              else

                              {

                                        stage.nativeWindow.restore();

                                        restoreIcon_mc.gotoAndPlay(1);

                                        MovieClip(this.parent).stageBackground_mc.width = stage.stageWidth; //stage is 1845

                                        MovieClip(this.parent).stageBackground_mc.height = stage.stageHeight; //stage is 1080

                                        this.x = stage.width * .91;

                                        this.y = 0;

                                        trace(stage.stageWidth, stage.stageHeight) //traces the size of the restored window

                              }

                    }

I don't understand why stage.stageWidth is the original window size(1280 800) when maximized and the maximized size(1845 1080) when restored.

Thanks
