Place butter in a Pam-sprayed 9-inch microwave safe pie plate. Heat, uncovered, on high for 1 minute or until melted, turning once. Stir in crumbs and sugar; mix well. Press onto the bottom and up the sides of plate. Cook, uncovered, on high for 1-1/2 to 2 minutes or until crust is firm and holds together. Cool completely. For filling, in a 2-qt. microwave-safe bowl, combine sugar, flour and cornstarch. Gradually return to the bowl, stirring constantly. Cook 1 to 1-1/2 minutes longer or until bubbly, stirring every 30 seconds. Stir in butter, vanilla and salt until butter is melted. Cool for 20 minutes, stirring several times.
