How Do Overdue Tasks Show On The Schedule?

A Due Date can now be set for Items in the Task Window.  When the due date passes, the item will be marked Overdue so they can be seen on the Schedule and Print documents. To remove the Overdue notice and turn that task black on the Schedule, clear out the Due Date cell.  

Overdue Tasks will also show red on both the Schedule view and Printed versions of the Schedule.
