MouseWheel Scroll not functioning to my liking

Ok I have implemented a zoom feature where you can zoom in/out by scrolling the mouse wheel…in the standard view, if the mouse is over the exhibitor list on the left, the map is not supposed to zoom when the mouse wheel is scrolled, but the list does scroll…this works fine as it should…when you switch to full screen view…when you have the exhibitor tab open, the mouse wheel scroll is only supposed to control the list component and not scroll the main map…this works fine locally from the flash workspace…however once I put it on the server…when the exhibitor tab is open…and you scroll the mouse on the list, the map zooms in and the list scrolls…this is crap and it shouldnt be happening…why does it occur online but not locally?

here is the code…

my mouse listener-checks to see if the mouse is over the tab…


var mouseListener2:Object = new Object();
mouseListener2.onMouseMove = function()
{
    if(tB1.list.exList.hitTest(_xmouse, _ymouse))
    {
        toolBar = true;
    }
    else 
    {
        toolBar = false;
    }
}
Mouse.addListener(mouseListener2);

//then this is the event listener for the mouse wheel scroll

var mouseListener:Object = new Object();
mouseListener.onMouseWheel = function(delta) 
{
    if(isLoaded && !toolBar)
    {
        if(delta > 0)
        {
            scaleUp();
        }
        else
        {
            scaleDown();
        }
    }
}
mouseListener.scaleUp = this.scaleUp;
mouseListener.scaleDown = this.scaleDown;
Mouse.addListener(mouseListener);

its puzzling that it works in the local environment and does not work online…any ideas why this may be? and any ideas on how to fix it?
