Could be the way they setup CSS and Partitions that they are not seeing
the same problems.

This person i'm helping did it this way to keep it
simple... they have another site with same route
patterns in other partitions that doesn't have this
issue for local calls. I'm going to try to get a trace
from them of that for comparison. WOuld think it would
have same problem since the patterns are same.
