I need to know whatever JS or lines of code Scirra puts into the Scirra arcade that prevents the keyboard from screwing with HTML5 games.
The fact that pressing space on the keyboard moves the user down the page is one reason I am getting 0/5 ratings on my game (remember, Newgrounds is a community full of little kids, and if things don't work they will give you 0 stars).
Space in my game is used to fire the ship. I have it mapped to a specific action, but this does not fix the problem because pressing space will still cause lots of people to scroll down the page (due to browser default settings).
I've built in the Arcade's workaround in to the runtime itself for the next beta, so hopefully that will fix it. If you view the source of the iframe page in the arcade, you should be able to see it calls preventDefault() and stopPropagation() on certain scrolling keys like space, arrow keys, etc.
