Windows Vista's Firewall offers false sense of security

Equally unhelpful was this explanation which tells us that it's about bidirectional blocking. Yet so far, we've seen nothing... not even a clue...as to how, for each program on that list we saw previously, to granularly configure inbound and outbound blocking independently of each other. Or, by adding a program to the list, does Vista simply block in both directions automatically and that's all there is to it? As it turns out, that's not the case. We know because we did a little test (next)
