I am trying to achieve an effect that I believe is probably fairly easy for the right person. Picture a flash movie with a crosshair pattern on it. In the middle of the cross hair I have a simple arrow which I simply want to rotate (staying centered), to point and follow the movement of the mouse on the screen. So basically all is said and done the arrow would be capble of rotating anywhere inbetween 360 degrees, depending on where the mouse is.

Any help or direction would be most appreciated.
If need be I can point you to a preview of the page I am trying to do this with.
