Follow mouse with ease.. but return on mouseout!

Hi guys

Ive been following this tutorial and have got it to work nicely.

http://www.kirupa.com/developer/mx/followease.htm

I need to modify it slightly so that when the user moves the mouse OUTSIDE the flash movie (i.e. in the HTML bits), the circle returns to a specified x,y coordinate in the flash movie. Lets say for arguments sake (25,25).

Any ideas on how I can achieve this?

Thanks in advance.
