Help please: can't get behavior script to work

Sat Oct 23 16:57:16 EDT 2010

Beware of mouseenter. In my experience, when the mouse is moving fast  
mouseenter sometimes doesn't get sent (this ought to be labeled as a  
bug). Mousemove is more reliable, though it will get called  
repeatedly. Unless you are doing something very complex on mousemove,  
however, it won't slow anything down.
