Choose how TimeSlice behaves when it starts.   When you double-click on the TimeSlice application icon, it can open a new document (same as selecting New from the File menu), display the file open window (same as selecting Open from the File menu), or neither. However, if you double-click on a TimeSlice document icon to start TimeSlice (instead of the application icon), only the file that you launch opens regardless of what is set here.
