I am a bit sick and took a 2 hour nap. That delayed skate: Flash Version. Anyway, I am announcing the sequel to AS3 Button Tut will be AS3 Cursor Tut. If you just wanna see the actionscript (without explanation) now, here it is (on frame):
import flash.events.MouseEvent;
stage.addEventListener(MouseEvent.MOUS E_MOVE , movecrs);
function movecrs(event:MouseEvent) {
cursor.x = mouseX;
cursor.y = mouseY;
cursor.visible = true;
Mouse.hide();
}

You have to figure out how to do this. For an explained actionscript with animation, check out the AS3 Cursor Tut tomorrow.
