\*Explanation:  
I`m trying to program a little Flash game involving a pullstring doll... however I`m having a problem involving mathemetics  
involving tangents… now you may wonder what pullstring dolls in  
Flash have to do with tangents…well… I`ll try to explain…

The Problem:  
I`m trying to create... a line between a certain point on the doll and a point on the circular "finger handle"... However... I don`t know how  
to make it so you can contuously set the point on the “circular  
handle” on the edge… on the tangent closest to the point on the  
doll…

In brief:  
At the moment the ends of the line are on the center of the doll  
(which is desired) and on the center of the “circular finger handle”  
(which is not desired)… as I`ve stated… I want the 2nd point of  
the line to be on the closest tangent point of the circle. to the  
center of the doll…\*  
So anyway… can anyone help me?
