my_mc.useHandCursor
Property; a Boolean value that indicates whether the hand cursor (pointing hand) displays when a user rolls over a button movie clip. The default value of useHandCursor is true. If useHandCursor is set to true, the pointing hand used for buttons is displayed when a user rolls over a button movie clip. If useHandCursor is false, the arrow cursor is used instead.
You can change the useHandCursor property at any time; the modified button movie clip immediately takes on the new cursor behavior. The useHandCursor property can be read out of a prototype object.
