Picking/Selection not working, Using Ortho2D

I have the following code:
void doSelect(int x, int y)
{
      GLuint buff[64] = {0};
      GLint hits, view[4];
      int id;
      int i;
      GLuint *names = buff;
      
      //set buffer
      glSelectBuffer(64, buff);
      glGetIntegerv(GL_VIEWPORT, view);
      
      //enter select mode
      glRenderMode(GL_SELECT);
      glPushName(0);
      
      glMatrixMode(GL_PROJECTION);
      glPushMatrix();
      glLoadIdentity();
            //Restrict area to around mouse
            gluPickMatrix(x-iw/2, y+ih/2, 5, 5, view);
            glOrtho(-iw/2, iw/2, -ih/2, ih/2, -1, 1);
            //DEBUG:
            fprintf(stdout, "Picking: Mouse at %d, %d +++ Picking Coords: %d, %d\n", x, y,  x, view[3]-y);
      glMatrixMode(GL_MODELVIEW);
      glInitNames();
      doRender();
      
      //restore normal views
      glMatrixMode(GL_PROJECTION);
      glPopMatrix();
      
      hits = glRenderMode(GL_RENDER);
      
            printf("%d hits:\n", hits);
       
       for (i = 0; i < hits; i++)
             fprintf(stdout,      "Number: %d\n"
                         "Min Z: %d\n"
                         "Max Z: %d\n"
                         "Name on stack: %d\n",
                         (GLubyte)names[i * 4],
                         (GLubyte)names[i * 4 + 1],
                         (GLubyte)names[i * 4 + 2],
                         (GLubyte)names[i * 4 + 3]
                         );
       
       fprintf(stdout, "\n");
      
      //restore to model view to render to screen
      glMatrixMode(GL_MODELVIEW);
}

Notice how the OpenGL coordnites is set to -Width/2 to Width/2 and -Height/2 to height/2, the mouse x,y are translated correctly, but somehow I am not registering any hits?

Am I doing something wrong?
