Composite circular dependency

Shilen,
 
I think I figured out what had happened.
 
It looks like I had a circular dependency in my groups:
 

• A = A_allow - A_deny
• A_allow = X + B
• B = B_include - B_exclude
• B_exclude = Y + A
   
  This last line was actually a mistake.  It should have been "B_exclude = Y".  The upshot was, when I added "B" to "A_allow", "B" was already in an unstable state.  I'm not sure how Grouper tried to resolve this, but I'm not surprised that the operations seemed to take a long time.
