onMouseWheel problem

Hi all,
I have a scrolling dynamic text, and I made it support mouse wheel also.
The scrolling text is part of a movie that loads externally (on _level2).
I am making a site with the main menu on a level, and the other pages load on _level2 (so all pages are loaded externally, including the page with the scroller). I am saying this because my problem occurs when I visit another page (load another page on _level2), and then I come back to the page that contains the scroller (load the scroller movie on _level2) the mouse wheel works wird, meaning it scrolls more than it did last time.
So the first time you visit the scrolling text page, the mouse wheel scrolls about 20 pixels with every scroll, if I press a button to visit another page and then come back, the mouse wheel will scroll about 60 pixels with every scroll, and so on. The distance keeps increasing, only if I go to another page and then come back. Weird ain't it? :D

Here is the code (the onMouseWheel code is at the end)

PHP Code:

Does anybody have any ideas on how to fix this?
Thank you so much :)

moved from the XML forum to the Flash Actionscript forum
(your problem does not relate to XML)

your question might get more answers here :D

Try clearing the interval before going to another page and/or removing the mouse listener.

Hi, and thank you for replying. I doesn't have to do anything with the interval, it just works weird. I can't really udnerstand why. I even tested it separately, without any extracode, just this:

PHP Code:

---

var mouseListener:Object = new Object();
mouseListener.onMouseWheel = function(delta) {
    test_mc._y -= delta
};
Mouse.addListener(mouseListener); 


---

And if this movie that contains the test_mc movieclip is loaded into _level2 for example, and you press a button and another movie is loaded into _level2, and then press another button to reload the main movie that contains text_mc, delta will get higher and higher with each time you do this operation. Every time you unload MC_TEST.swf - load another movie.swf - then reload MC_TEST.swf (where MC_TEST.swf is the movie that contains test_mc), when you scroll once, you scroll larger and larger distances. It's really weird.
Anybody experienced something like this before?
