In Method One, the empty movie clip is actually a seperate movie clip than the one you load on.
But now that I think if it, I am not sure if it will work if you apply the code to the clip on the stage you are loading too… Interesting… I never thought about it. It is worth a try
In Method Two, “checkFrame” is the instance name of the empty movie clip dynamically created.
Then _root.checkFrame.onEnterFrame = function() creates an event handler for the checkFrame movie clip. In this case, the event is the onEnterFrame.
