Too many key checks, both UP and DOWN, maybe?? Thought one: =========== Rather than this way.. key_listen.onKeyDown = function() { switch (Key.getCode()) { case Key.SPACE: break; case Key.LEFT: break; you could try this, keyListener = new Object(); Key.addListener(keyListener); keyListener.onKeyDown = function() { var kc = Key.getCode(); switch (kc) { case {your keycode as integer}: break; // some code case {your keycode as integer}: // some code break; // etc, etc. }; That was the way I did it for the pdf viewer part of that scrappy media player. It also allowed me to use 'toggle' keys as well, which, amongst other things might solve your going to full screen issue. Thought two: =========== Had you considered embedding your sound file as an swf rather than an mp3? Regards, Chris. -- Chris <[email protected]>
