Mouse_wheel

Hi !!
I have a problem that i can’t solve. On the main timeline a have only one keyframe with action in it.


[COLOR=#0066cc]stage[/COLOR].[COLOR=#006600]addEventListener[/COLOR][COLOR=#66cc66]([/COLOR]MouseEvent.[COLOR=#006600]MOUSE_WHEEL[/COLOR],onWheel[COLOR=#66cc66])[/COLOR];
[COLOR=#000000]**function**[/COLOR] onWheel[COLOR=#66cc66]([/COLOR]evt:MouseEvent[COLOR=#66cc66])[/COLOR][COLOR=#66cc66]{[/COLOR]
[COLOR=#66cc66][/COLOR]    [COLOR=#0066cc]trace[/COLOR][COLOR=#66cc66]([/COLOR][COLOR=#ff0000]"onWheel"[/COLOR][COLOR=#66cc66])[/COLOR];
 [COLOR=#66cc66]}[/COLOR] 

…well, the thing is, that I have to click anywhere on the stage and then use my mouse wheel in order to see trace statement. When I don’t click on the stage nothing happens, the same thing is with a movieclip !! Why does this code doesn’t work ??

Please help !

Is there a way that I can use my mouse wheel without first clicking the stage ?
