OK, I am confused a little.  I understand your point that the VSS layer is not 
in the routing "pair" and perhaps that is the real problem.  It would be nice 
if the autorouter understood connecting to underlying zones.  I will try 
autorouting and tell it the layer pair is my component layer and the VSS layer 
and do an autoroute.  Then try the same with the component to VDD/VCC3/... 
layer.


On a related note, I found what I think is a bug.  i will try to check the bug 
list to see if I can find it.

My edge connector has several GND pins that are used to supply power to my 
board.  I defined the pin name as GND, no draw, Power OUT.  EESchema refuses to 
automatically connect it to the GND net.  I change the pin to Power IN and 
EESchema immediately says it is connected.  The manual says Power IN or Power 
OUT are supposed to both work to automaticall connect.

A wild guess here, as I've never done anything like that :-)

How does the system know that you can get to the VSS layer from the
component layer?

If things work with a DIP, would placing a via do the same job?
It would seem logical to me that if you want to route to an inner layer
then you need to place a via between it and the component layer.

I'm not sure if this can be done automatically 
(there is a way to pair layers for via use section 5.4 of the help)
