WDT and mini pro Arduino

I have been working with a Arduino UNO clone and was using WDT in my sketch.

I then swapped to a Mini Pro and when my WDT was activated ( due to a lack or a reset) the mini pro board seemed to crash. Pin13 LED would flash quickly untill I held down the reset button. Upon release of the button the LED would flash again. I had to power the board down to reset it.

Does the Mini pro support WDT? If so is it different from the UNO?

Thanks
