Creating new shapes: Possible Bug? Or my fault?

[Reed Hedges <reed activmedia com>]

Hello,

I've created some new shapes, and added them to a new sheet. But when I use them 
in a diagram, Some of the components of the shapes seem to be conected to a 
corner of the shape by extra lines.

One possible clue is that some of my simpler shapes don't exhibit this problem. 
 One difference observed is: in making the more complicated shapes, I 
duplicated objects like boxes and circles, while my simpler shapes without the 
problem are just a couple of polygons or polylines without any duplicates?  I 
haven't specifically tested this hypothesis, merely observed it.
