1pixelout player closing

Great new auto-close feature when there are multiple players on a page, been wanting that for a while! When I add a player to a page using the swf() call, and pass in any parameter, my players are being forced shut as they open. E.g., loop through all files for a node and call:

$audio .= swf($file[filepath],
  array('flashvars' => array('lefticon'=>'0xFFFFFF', 'righticon'=>'0xFFFFFF', 'text'=>'0xFFFFFF', 'bg' => '0xADADAD'))
);

It renders fine, but then when I play the file, it immediately closes the player and shuts off.
