That may be the way it's supposed to work, but it doesn't for me, at 
least on Windows in windowed mode. All that happens is the coordinates 
reported by mouse_x/y are clipped to the range you specify.

Here's the program I used:

--
#include <allegro.h>

int main(void)
{
   allegro_init();
   install_keyboard();
   install_mouse();
   set_gfx_mode(GFX_AUTODETECT_WINDOWED, 800, 600, 0, 0);
   show_mouse(screen);
   set_mouse_range(50, 50, 300, 300);
   position_mouse(100, 100);

   while (!keypressed()) {
      printf("mouse_x=%d mouse_y=%d\n", mouse_x, mouse_y);
   }
}
END_OF_MAIN()
