Traverse closure issues

We are still having bad traverses according to 2007. If we
process the traverse in 2006 it is fine. I'm not sure why 2007 is reducing
the traverse incorrectly, but what we are seeing is that 2007 reports that
there is a closing angle error anywhere from 110 to 120 degrees. When we
process it with 2006 there is only a 10 second error. I don't understand
what is going on.
Another question! Does Survcadd 2006 work on Autocad 2007?
