I have a Flash application that have to detect the mouse wheel event (MouseEvent.MOUSE_WHEEL), I've tested on a stand alone flash player and works perfect, but when i put the swf in a web browser, the mouse wheel stop working.
I've tested this in: Internet Explorer 7.0, Mozilla Firefox 3, Safari 3 and Google Chrome; and this behavior happens in all of the browsers
PS: The swf file is embed in the body of the page, a simple page with only the swf.
EDIT: The swf has wmode set to opaque and it has focus on it when this bug happens.
