Full screen Air app from Flash

Hi,
Im using Flash CS3, and I´m trying to make my first AIR applications.
I try to get a full screen view using:
stage.displayState = StageDisplayState.FULL_SCREEN_INTERACTIVE;
but i only get a full screen window. Can´t get rid of the window/menu-bar and the system bar on top (I´m using OSX).
I think I have to disable the systemChrome, but I can´t figure out how to do this from Flash. I´ve seen som AIR examples in javacript and flex, but nothing that works for me in Flash.

Best regards
Peter
