you got *2* readkey() calls in the code, what do they use, the sattelite
dish?

use better code. use structured programming. what happens if the user
clicks outside of any of the 2 rectangles for example?
this code will work better. it looks bad, I just cut-n-pasted from your
code.

#include <stdlib.h> /*for good luck*/
#include "allegro.h"

int main()
{
   allegro_init();
   install_timer();
   install_keyboard();
   install_mouse();
   set_gfx_mode(GFX_AUTODETECT, 640, 480, 0, 0);
   set_palette(desktop_palette);
   clear(screen);
   rectfill(screen, 10, 10, 150, 40, 7);
   rectfill(screen, 10, 300, 150, 480, 27);
   show_mouse(screen);

while(1)
{
   if ((mouse_x>10 && mouse_x<150) && (mouse_y>10 && mouse_y<40) &&
(mouse_b&1))
   {
   sound(400); /*The sound and delay are just in case I forget to look
at
the exit code*/
   delay(500);
   sound(0);
   return 0;
   }
   else
   if ((mouse_x>10 && mouse_x<150) && (mouse_y>300 && mouse_y<480) &&
(mouse_b&1))

   {
   return 55;
             }
}

}
