With the new list system and overhauled word popup just released, there are a handful of bugs floating around that slipped through. I'm fixing them as they come in, and by the weekend the vast majority of lingering bugs should be gone. And if you see something amiss, let me know at scott at skritter.com or post it on this topic and I'll address it right away.
If you're curious about the new features check out last month's newsletter:

More info to come on the blog! As soon as I stop frantically smashing every bug that emerges :)
