XP buggers up my speeds

[THSH]

I put a javascript game on my website, and it works fine on ME and earlier OSes, but not XP! The speed is uncontrollably fast! Can anyone help me slow it down a bit please, as I'm not a java expert?

Please post your code.

There are several parts to the code - the game is on this page (http://geocities.com/thehumourstopshere/game/blocks.html) if anyone could take a look please?
