There are multiple uses of this function below - shouldn't those use
window.removeEventListener() now?

-{
-  // all IE versions require the use of detachEvent for message event to work
-  if (type != "message" && "removeEventListener" in object)
-    object.removeEventListener(type, listener);
-  else
-    object.detachEvent("on" + type, listener);
