Ok I have been working with the onEnterFrame handler for a while but I still dont have a good grasp of what it does. Does it execute whatever code is written between the brackets every time the movie enters a new frame? Or does it just keep executing the code constantly. And how do I clear the code I wrote inside these brackets so it wont execute later?  
It is just delete this.onEnterFrame ? A brief explanation of what it is and how it works would be greatly appreciated. I didnt get much from the help file.

If enter frame only executes while the timeline is moving, how come this file still works?

Everything inside the event handler will run at the speed of FPS, thats frames per second of the movie.

Ok so the event handler runs independent of the timeline. So its sorta like a movie clip in that it does its on thing at 12fps or whatever
