Oh, I forgot that the script also adjusted the due date! So you want the task to retain its original due date, and just shift the start date?

You could replace this line:

					tell oTask to set {start date, due date} to {newStartDate, newDueDate}

with this line:

					tell oTask to set start date to newStartDate

and I think you would get the desired result (start date adjusted, due date left as it was).
