Quite right. It has been years since I've had it installed. Now that you've reminded me, I do remember the bobbing of the ship, just not anything like the scale I'm seeing now. Of course the last system I actually ran this on was either a DX4-100 or a Pentium 200; a far cry from the 2000 MHz machine I'm trying to run it on today.
Thanks for pointing me in the right direction.
