Good news! I figured out how to get the Direct Messages working. Recall that due to a recent change in twitter’s API policy, direct messages stopped working a few days ago.
Better news. You don’t have to download anything new.
Not so good news (you knew there had to be a catch). You’ll have to reauthorize the gadget to get direct messages working. That simply means closing the gadget, opening a new instance and getting a new PIN.
What changed? Twitter issues API keys to client programs like tweetz. Tweetz’s application key is associated with a set of permissions as to what the application key is allowed to access. I simply had to add the ability to retrieve direct messages to the application key’s configuration.
