2.43_Physics Error

Help. I am making a basic physics test in blender. I have the cubes set up, and they look fine in the game engine. However, when I tell it to record to IPO, it messes up. Please help. Here is the blend file, left click the link. And if it helps, I use windows xp.http://one.fsphost.com/brucem91/physics_test_1.blend
