Following up on this conversation.  Yes, what we'd like is an
interface like that available on the Mac.  It is similar to the
interface available on our home-grown K4-only Kerb95 client.  Is
there any plan to update the Windows interface to match the Mac's?

I understand there may be resource issues.  What if Michigan were to
offer up the resources to update the Windows interface?  Could we
expect that the changes would be integrated into the KfW distribution?
