I have a simple drag and drop game started in flash and mostly working.
I have added my animals and you can drag and drop them in the right place.I have also added sound
Look at your MouseUp event handlers.
You are adding the event listener to the stage. So they are all getting called whenever the stage hears a mouse up event.
Add those listeners to the cow, pig etc just as you did for the mouse down listeners.
That should solve it.
Pig.addEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToDrag);
function fl_ClickToDrag(event:MouseEvent):void
{
Pig.startDrag();
}
//stage.addEventListener(MouseEvent.MOUSE_UP, fl_ReleaseToDrop);
// change to this
Pig.addEventListener(MouseEvent.MOUSE_UP, fl_ReleaseToDrop);
