How do i do a flicker and have the mouse pointer not change

I’m trying to make a movieclip, button that when the mouse goes over it. It will flicker really fast then when the mouse moves off of it it will stop flickering. My problem is that when I do the flicker it will change the mouse pointer from the hand sign to the arrow sign.


on(rollOver) {
	clearInterval(flicker);
	flick = function (mc) {
		mc._visible = !mc._visible;
		updateAfterEvent();
	};

	flick = setInterval(flicker, 5, btnTest_btn);	
	
}

on(rollOut) {
	clearInterval(flicker)
	if(!btnTest_btn._visible) {
		btnTest_btn._visible = true;
	}
}

```php
 

It works ok but if i could get the mouse pointer to stop switching that would be awesome

Thanks
