Stage resize help, Mac vs Pc issues

Hello I need help. I have fullscreen flash sites using the kirupa tutorial found here: http://www.kirupa.com/developer/mx2004/fullscreen.htm

The sites look good on a mac but are cutt of at the top and bottom on pcs. (Depending on the resolution and the size of the screen).

example: tmanningphoto.com

Is there a way to use the resize function or the stage.LT or TL to ensure that the sites look the same on both platforms. any help would be appreciated.

thanks
