I ve been trying to blit one colour to the screen using the code below but
it doesnt work (this is my first c/c++ proggy). All it does is display a
small band of the colour on the top of the screen ( its about 4 in wide).
Can anyone tell me why this isnt working because i think it should.

#include <stdlib.h>
#include <stdio.h>
#include "allegro.h"

int main()
{
   BITMAP *memory_bitmap;

 /* allegro init stuff (video and keyboard routines) */
   allegro_init();
   set_gfx_mode(GFX_AUTODETECT, 320, 200, 0, 0);
   set_pallete(desktop_pallete);

 /* make a memory bitmap sized 320x200 */
   memory_bitmap = create_bitmap(320, 200);

/* draw something onto it */
   clear_to_color(memory_bitmap ,0);

/* stick it onto the screen */
   blit(memory_bitmap, screen, 0 ,0 ,0 ,0 ,320 ,200);
    return 0;
}


Thanks
