geometry compare - incorrect results

Hi -

I'm running SW2010, X64, SP4.0.  I'm using the geometry compare and I am getting results that are completely wrong.  It is missing huge chunks of geometry that I know have changed.  Is there an ongoing bug for this add-in?  I've dumbed down (surpressed) geoemtry between the two files so I'm only looking at the geometry that I know has changed.  The models are not terribly complex.

Is anyone else getting incorrect results?

Any help is appreciated.  Thanks

Joe
