Remove event listener

1

do you have to ask before you try to remove some listener:

**if(hasEventListener(Event.ENTER_FRAME)) {**
   removeEventListener(Event.ENTER_FRAME, panThumbs);
}

or you can just say somewhere in your code:

removeEventListener(Event.ENTER_FRAME, panThumbs);

and if it has listener at that moment it will be removed and if it hasnt no harm, right?

or not? :smiley:
