Object follows mouse with ease only when moused over

i have been trying to figure out how to make an object move when its moused over.
once moused over, i would like for it to move with an ease (penner), but once the mouse is off the object, i would like it to ease into a dock position.

i have been using penners code…

[COLOR=“DarkRed”]function glideToMouse () {
this._x += (_parent._xmouse - this._x) * .2;
this._y += (_parent._ymouse - this._y) * .2;
};

this.onMouseMove = function () {
this.onEnterFrame = this.glideToMouse;
};[/COLOR]

but this works for where the mouse anywhere in the movie. i only want the object to move when it is moused over.

hope this makes sense.

thanks,

paul
