DOMContentLoaded Problem for cross browser and a window.setTimeout solution:

function DOMReady(f){
  if (/(?!.*?compatible|.*?webkit)^mozilla|opera/i.test(navigator.userAgent)){ // Feeling dirty yet?
    document.addEventListener("DOMContentLoaded", f, false);
  }  else {
    window.setTimeout(f,0);
  }
}
