ActionScript 3.0 :: Previous As Mouse Over Equivalent

create a new flash project, draw whatever and call it 'a'. then paste this:[code]this is a simple handler that should trace 'here' while the pointer is over 'a', thats all. if you run it, it will trace 'here' only once, or only once every time you enter a, instead every frame the pointer is over a.how do i create a handler that runs as long as the pointer is over a sprite or whatever. a way could be to put an enterframe and check if the pointer is over a, which i believe is not decent at all, is there any equivalent of 'over' that runs while is over, and not just enter?
