nanogui: Thread: What am I doing wrong? Images not displayed....

I've go the following piece of code:

        window_id = GrNewWindowEx(GR_WM_PROPS_APPWINDOW, title,
                GR_ROOT_WINDOW_ID, 0, 0, w, h, GREEN);

        GrSelectEvents(window_id,
                GR_EVENT_MASK_CLOSE_REQ|GR_EVENT_MASK_EXPOSURE);

        GrMapWindow(window_id);

        gc_id = GrNewGC();
        GrDrawImageToFit(window_id, gc_id, sx,sy, w,h, image_id);
        sleep(SLEEPTIME);
        GrDestroyWindow(window_id);
        GrDestroyGC(gc_id);
        GrFreeImage(image_id);
        GrClose();
        exit(0);

What is supposed to happen is that the image is displayed for SLEEPTIME, 
then the viewer exits.

What is happening is that the viewer sleeps for SLEEPTIME on the green 
screen, then updates the screen displaying the picture, and then exits....

I must be missing some sort of magical update screen function, but I 
can't find it...

Do a GrFlush() to force the client to flush its command queue to the  
server before you sleep().

If it doesn't work, you're not hitting it with a big enough hammer
