This annoying message is sent by the [processMenuItem:] method (in class AlphaMenuItem) when the command executed returns a failure code (cancelling a dialog, like the preferences dialog, precisely emits this failure code). This was just meant as a sentinel when I was developing this part of the code. It is not necessary anymore and I just removed it. I just committed the fix to the repository. Thanks for reporting.
