How do I get back the old 'square' task box - MM2012 has circles which I don't think are anywhere near as good.
As I am sure you are aware, the square task icons were part of MindManager 8. There is no way to change the progress markers from circles to squares in MindManager 2012. If you would like, you can make this topic an idea and our product team would be happy to review it as a feature request for upcoming releases. Thank you!
