Can someone please, please, tell me what is wrong with the above code.
I use it as a teaching tool so I need to know every possible thing that could
be wrong with it. Please, I need someone who will seriously look at it and
tell me what’s wrong, whether it be a coding best practice issue, a garbage collection
issue, programming or whatever. The code works, but according to one person,
it’s laughable, and I really need to know why. As of now my 8+ years of ActionScript
programming have been laughed at, and I need to know why.

There is really only one person who I trust to give a good answer, he has 6 eyes.
But everyone else please let me know what you think of the above code, good or bad.

Thanks
