}
//set up the handler for our event
//make sure to type in "sml.mouseEnabled = false;" or your buttons might not work right

//––––––––––––––––––––––––––––––––––––

//to get your mouse to come back you should add "removeChild(sml);" and "Mouse.show();"

//For example, you can add it to a button:

button.addEventListener(MouseEvent.CLICK, clickHandler);

function clickHandler(evt:Object):void {
removeChild(sml);
Mouse.show();
gotoAndPlay(27);
}
//you can also add Mouse.show(); to the actions on another keyframe
