Thanks, but I don't think I'm running into this -- yet. I'll keep it in mind.

I was mistaken when I said that the float coercion is working. After 
struggling with Mesh.Cylinder to no avail, I wrote a very small test 
assembly in C#:

using System;
using System.Collections.Generic;
using System.Text;
using System.Windows.Forms;

namespace ClassLibrary1
{
    public class Class1
    {
        public Class1()
        {
        }
        public static void Yop()
        {
            MessageBox.Show("I am here! I am here!");
        }
        public static void ShowSingle(Single f)
        {
            MessageBox.Show(f.ToString());
        }
        public static void ShowDouble(Double f)
        {
            MessageBox.Show(f.ToString());
        }
    }
}

(I'm using VS 2005, thus .NET 2.0. Not that it should make much difference.)

Yop is used as a sanity check, and it works. I can successfully call 
ShowDouble with *c-d-f-t-s* nil. I can call both ShowDouble and 
ShowSingle with *c-d-f-t-s* t, but *both* show an incorrect result.

I haven't fetched the source for the RDNZL DLL yet, but I think that's 
my next step.

BTW, do you know any way (in Lispworks!) of forcing an assebmly to 
unload, so I don't have to restart the Lisp image whenever an assembly 
is changed?
