STM32F4Discovery entering debug requires holding reset

I have been working with an STM32F0Discovery Board where entering debug mode simply requires pressing the "Make & Restart Debugger" (green arrow) button in IAR. 

With the STM32F4 discovery board, the STLink will not identify the target MCU unless I hold down the reset button until the "starting debugger session" pop-up appears. Then, upon releasing the reset button, the debugger proceeds to download to flash and enter debug mode. This seems like strange behavior to me. Is this normal?
