Block_Redux fails to render - workaround

What steps will reproduce the problem?
1. Open BlockRedux in Chapter13
2. Compile and run Block_Redux in Chapter 13

Expected: see the wireframe block on the floor
Got: just a white diagonal line bisecting the screen

What version of the product are you using? On what operating system?
oglsuperbible5 svn r176
Visual Studio C++ 2010 Express
Windows 7

I have a workaround for this issue: force the program to create a lower-level 
rendering context, viz:
        g_hRC = wglCreateContextAttribsARB(g_hDC, 0, attribs);
        if (true || g_hRC == NULL)
        {
            printf("!!! Could not create an OpenGL 3.3 context.\n");
            attribs[3] = 2;
            g_hRC = wglCreateContextAttribsARB(g_hDC, 0, attribs);
            if (true || g_hRC == NULL)
            {
                printf("!!! Could not create an OpenGL 3.2 context.\n");
                attribs[3] = 1;
                g_hRC = wglCreateContextAttribsARB(g_hDC, 0, attribs);

.....presumably the cause of this problem is that a higher opengl version is 
being reported than the program can create a context for. I don't really 
understand the implications, or whether it should means the driver is incorrect 
or that the program should be changed, but perhaps this post may be of some 
help to others.
