Hallo Carl,

I did exactly your lines of code on a NT machine running Mathematica 3.0.

My output is
837760
941952
941952
941952
941952
941952
941952
941952
941952
941952
So it seems to stay constant except the first one.

I hope I could help you. I could give it another trial on the Win98 machine
with version 3.0
