I posted a message a while back ("My program's a machine killer") about my
machine rebooting when using the clear_to_color() function.  Someone replied
saying that the code worked fine on their machine, but when I run it on my
computer, it reboots. It didn't start doing this until I started playing
with the clear_to_color() function. The code is below. Anybody have any idea
why this is happening? Anybody else have the same problem?

Thanks,
Brian

#include <stdio.h>

{
    static char *strings[] =
    {
        "Entry 1", "Entry 2", "Entry 3"
    };

    if (index < 0)
    {
        *list_size = 3;
        return NULL;
    }
    else
        return strings[index];
