1. Have you debounced your switch? 2. if Interrupt 0 is Level triggered it will execute again if leveis still low on the /int0 pin after the ISR been completed. this is because, if intx is level triggered the request flag is controlled by the external source and not cleared by the hardware so you have to hold the low level untill int is actually occurs and remove the low level before CPU exits the corresponding ISR.
