Ok, now I'm super curious as to what the problem really is. I tested this on 2 different machines and got the same result.
Mordy posted a test which was run on an awful lot of machines. Trust me, it's not reliable, and Skidracer himself confirmed it, if memory serves. You'll get the same results from most of the people, but not all the people. When you're using it for procedural content generation, or fractal seeding, you need it 100% and it's just not.
