One bug

I really like this game, its a lot more interesting than just spinning a wheel. I also like it because I can showcase my knowledge on subjects I know Im good at.
The one thing Im having trouble with is that when I am going to pick an answer, if the correct answer is the last choice, or D, then it will not, no matter what, let me choose that answer. I have lost several rounds on different games because it wouldnt let me choose the right answer. That is my only problem as of right now.
