Question: number - too large - maple wouldn't interrupt

I did evalf(3^1000000,1000) or something like that on a laptop.  It was taking a long while so I pressed the interupt (stop hand) button.  Nothing happened, it didn't stop.  It did finish what it was doing but it didn't immediately stop.

Unless it was trying to update the screen with all the numbers I think maple should have just stopped whatever it was doing and give me back control.  

Please Wait...
