Playing igowin / Many Faces of Go

So I downloaded and played igowin when I first started looking at computer go (about when I started this blog). For a time I played the little 9x9 regularly, maybe a couple of times most days for maybe 6 months. then I odn't play it for maybe eight months, try it again (the same installed version), and I'm two stones stronger against it, without playing go in the intervening period. I suspect that I'd slipped into dreadful point-and-click-without-thinking habits when I was playing it regularly.
