Display List problems

OK, I am writing a program in Visual Studio 2005 that has a ball class defined like this:

#ifndef BALL_H_
#define BALL_H_
class ball
{
 public :
     ball(float r, int g, float re = 1.0, float gr = 1.0, float bl = 1.0, float xpos = 0.0, float ypos = 0.0, float zpos = 0.0);

     virtual void draw();

     ~ball();
 private :
 protected :    
     float radius;
     int granularity;
     float x,y,z;
     float red, green, blue;
     GLuint BALL;
};
#endif 

#include <windows.h>												// Header File For Window
#include <gl\gl.h>													// Header File For The OpenGL32 Library
#include <gl\glu.h>													// Header File For The GLu32 Library
#include "ball.h"

ball::ball(float r, int g, float re, float gr, float bl, float xpos, float ypos, float zpos) :
    radius(r),
    granularity(g),
    red(re), green(gr), blue(bl),
    x(xpos), y(ypos), z(zpos)
{
    GLUquadricObj * tempBall;
    tempBall = gluNewQuadric();
    BALL = glGenLists(1);
    glNewList(BALL, GL_COMPILE);
     gluSphere(tempBall, 1.0, granularity, granularity);
    glEndList();

    gluDeleteQuadric(tempBall);    
}

void ball::draw()
{
    glPushMatrix();
      glColor3f(red, green, blue);
      glTranslatef(x, y, z);
      glScalef(radius, radius, radius);
      glCallList(BALL);  
    
    glPopMatrix();    
}

ball::~ball()
{
     glDeleteLists(BALL,1);
}

And a render function that looks like this:

bool DrawGLScene(GLvoid)								// Here's Where We Do All The Drawing
{	
	glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);	// Clear The Screen And The Depth Buffer
		
	glLoadIdentity();								
	glRotatef(-yrot,0.0f,1.0f,0.0f);
	glRotatef(-xrot,1.0f,0.0f,0.0f);
	glTranslatef(0.0f,0.0f,z);
    


    theBall->draw();

    return true;
}

And it won't draw the sqhere. Now, if I put the code to draw the sphere directly in the draw() function it works, but it cannot call the list. I step through the code while running and I can see it does complete the glCallList function, but nothing happens. I've also tried to call the list directly in the DrawGLScene(GLvoid) function and that doesn't work either. Although if I compile a display list in that file and call it in DrawGLScene(GLvoid) it works. Any thoughts on this? This is killing me.
