Rollover question

hello,

im relatively new to flash8 action script. but i do a good deal of oop application development at my work. im trying to figure out a way to do some action script on rollover. but i want the action to loop when the mouse is overtop. not just once when the mouse initially hits the object. like as if to continually rescale an object while the mouse is hovering over the object. or to make a button move to a random position when the mouse is overtop. was curious if anyone has an easy way to do this. in the meantime ill be searchin around for the proper method.

thanks,
:sen:
