Kongregate adds scrollbar to my game! Help!

My game is 800*480, so it should be supported by Kongregate. (right?) The problem is that Kongregate adds scrollbars to my game. Anyone knows a solution? :(

Weird! I'd contact kongregate about this. I didn't have this problem (although my game was 800 * 600)

I've had it happen, too, and found a quick way to fix it. When you edit the game details, add some "padding" onto the width/height parameters. In your case, try 820 width and 500 height.
