Not sure. Either it's failing to connect to check for updates, or at some point you deleted all of the scheduled task triggers for it. If it is the latter, you won't be able to do that anymore with 4.1.
Come to think of it, I believe I did delete the task as I initially wanted to keep the landscaped images on the Home screen.
