I don't understand what you wish to achieve to be honest.
You say you want to display information on a mouseover

But your code, has nothing to do with displaying information.

So my question is: What is it you wish to achieve?
a) Display information on a mouseover mc? (If this option what information, ie string, mc or other)
b) Rotation of mc? (What type so the mc rotates to face the mouse or so the mc rotates all the time, just depending where the mouse is what speed and direction)
Also if option 1 of a, in the same direction all the time or the shortest direction to rotate in.
Or do you which to achieve both a and b?

Just need more information.
