avoid accidental use of gold bars

It has happend for the fourth time in a few weeks now. Every time I manage to save more then 10 gold bars I loose them in no time because I accidentally touch the large green button that asks you whether you want to play further. Immediately you loose ten gold bars if you touch that button. I think that is not fair. You should ask for confirmation before taking the gold bars. It costs 3 dollars per ten gold bars so really annoying that King organized it like this.
