I have an application with an fullscreen button, when that button is clicked I change the displayState of stage to StageDisplayState.FULL_SCREEN_INTERACTIVE.
StageDisplayState.FULL_SCREEN_INTERACTIVE
It seems like this is a bug limited to the debug player.
Debug version of Flash Player 11.1 reproduces this bug, while the Chrome version 11.2 and browser plugin 11.1 does not.
Use a boolean. For example, make it true in the resize function and check if it's not true to execute it.
