I have a Flash presentation (made in Flash CS4 with AS3) I am working on and running in a standalone Flash player. When I start the presentation the stage is centered in the Flash player, even if I resize it. The presentation contains an FLVPlayback component which, at different frames, plays different content. A navigation menu (made of buttons) is used to move through the different frames.

My problem is that if the player is resized so that it is bigger than the stage, sometimes after going into and exiting from fullScreen mode, the stage is moved to the left and I cannot find a way to move it back to the center. I cannot stage the scale as the content becomes distorted and I do not want to force fullScreen all the time. I would just like to center the stage in the Flash player.

Is such a thing possible? Any help is greatly appreciated.
