Can you elaborate on this question?
What tasks are you running? What do you mean by ordinary shutting? Do you mean just pressing the abort button in the menu bar?
If you have any hardware operations, it is not recommended that you stop the VI by pressing the abort button. It would be better to have a Stop Boolean. Since you have LabVIEW 6.1, you can use the Event Structure. Have a event case for Stop, and end all of the tasks in that case.
