I have to admit that until yesterday I had only stalled once and I just pressed the key and off we went...
However, in a moment of weakness yesterday I tried to take off in 3rd and stalled before I realised... I pressed the key... nothing. I pressed it again... nothing... I then paniced, took the key out, re-inserted it, then pressed it again... NOTHING! Thinking I had killed the car, my heart sank and I took my foot off the clutch... Then I thought I would try one last time... depressed the clutch, pushed the button... VROOOOOOM... Screeeeeeeeeeeech... we were off in coulds of blue tyre smoke... My doing, not the cars!
So in summary, it appears that on occasions, the electronics needs you to release and repress the clutch... bear that in mind if you press that buttom and are met with silence!
