Somehow when I have played pinball FX 2 for a while on my surface pro 4 it does not seem ta react to my keyboard any more. I can start a new game by clicking with my mouse on the wanted pimball field, but then I have to push the launch button (down arrow on my system) but somehow the entire configureation does not react. Other programs work fine. What is going on here?

I am using a surface pro 4 I5 with the newest windows 10
