First of all, I still have the issue with them flying up. This is not supposed to happen. I think there might be a Windows XP vs Vista issue. What am I supposed to do: all our school computers are XP, and I can't tell my teacher "Oh, it works at home, but it doesn't at school." Regardless of the fact that it does work at home, and not at school. Thank you for reminding me you can reduce the speed. The issue is that when opened in greenfoot, a max slider setting behaves at a reasonable speed. It does not make sense to me that when it is on an applet, I need to reduce the speed, which also controls the frame rate in my game.
