ActionScript 3.0 :: Accessing AddEventListeners In Child?

i have to make a drag and drop thingy in actionscript 3.0. Now we had another actionscript project before and then i had some extra classes but most things i put in the main class and it was all working fine. Someone told me that i put too much in my main class and that i should make more classes like a class for every object you interact with. Dont know if hes right but he acted like he was.

Now back to the problem. I made a main class connected directly to my fla in its properties. Then i made another class for the game itself, cause maybe it needs an intro and other things so i want to separate them in their own classes and start them with the main class. now in the class for the game itself i want to be able to click an object with the mouse. I was just testing with a trace. When i click the object it only traces like 1/20 clicks i make, tryed alot of things, when i put the same code in the main class with stage.addEvent blabla it will respond every time but as soon as i try to put in the class for my game it only responds like 1/20 times i click. Wth?

Now i can put all my code in the main class again and make another 1000 line code with a couple of other small classes but this time i want to do it right so what am i doing wrong? Heres some code too

This is the main class dressUp is the game class, it doesnt do much just define the game class and change the mouse pointer.

EDIT: We work in a project group so another reason i want to make alot classes is so we can work on different classes separately. But i promised to have this done this weekend and there not so good in actionscript either.

ActionScript Code:
package
{
import flash.display.*;

[Code].....
