*pokes at board* Why you not showing properly?

Nevertheless, today's step was nasty! I have completed it, but I now have a very achey left clicky finger.

My strategy was to get all the one codes out of the way, then go through doing some twos until a three stopped having that 'incomplete data' message showing. Then I shamefully used a decoder (whose creator has now been frozen for cheating.. leetle bit scared here) and the desired message showed up on my second try. Hurrah.
Plus, of course, I threw in a heavy sprinkling of perseverance. Hey, if a pre-teen can do it, then so can I!
