Is there any way of making a sprite invisible on the stage,
but still keeping it active so that the mouseEnter handler will
still work? I want to create tooltips so that as the user moves the
mouse over a part of the image that part is highlighted by a
rounded-rect sprite and the tooltip appears. I could double up the
sprite by having an additional zero-thickness rect sprite to sense
the mouse, but that seems inefficient. I thought I could make the
sprite invisible until the mouse entered it, but switching off
visibility also switches off the mouse's awareness of the sprite.
Thanks for any help.
