Thanks for Due, I use it all the time. I just found a bug in Due Mac.
Steps to reproduce:
-- Command-N to create a new reminder
-- Type "test" in the title field
-- Press Tab to navigate to the "Due date" field.
-- Type "noon"
-- Press Enter
Due shakes to indicate that it doesn't know what "noon" means
-- Press Enter again.
Due crashes.
Due shouldn't crash, but also it should know what "noon" means!
