Why do my arrow keys appect my scroll bar?

By default, that is the function of the arrow keys; to scroll. If you want to prevent this while playing a flash game on the Internet Explorer, simply click on the game first. Anywhere at all, as long as it's on the game is fine and your arrow keys should return to normal function. Also if you scroll down the page or switch tabs while the game is on, you still have to re-click the game every time. Hope this helps!
