Hi, let's say I have a 40 by 40 pixels square (at 0,0) on the screen.  I
use Allegro for my mouse routines and I currently use a do/while loop to
see if the mouse is over this square, but it's very slow and
inefficient.  Can someone suggest me a better way with example?

Here's way I do:

do
    {
    for (int x = 0; x = 40; x++)
       {
        for (int y = 0; y = 40; y++)
            {
             if (mouse_x == x && mouse_y = y)
            outtext(screen,font,"Bla",1,1,COLOR);
             }
        }
    } while (keypressed() != 0);

Sorry for my coding habits...  Nicolas Blais
