Hi
I had a problem with Allegro2.2, every time i use the alert() funtion the
textout() function gets another background color, from black to with and
vice versa, and i don't know how to change the background color of the text
output.

Here is a example Programm which demonstrate the problem:

/* PRG BEGIN */
#include <allegro.h>

int main()
{
 RGB grey[256];
 int i;
 int c;

 allegro_init();
 install_keyboard();
 install_timer();
 install_mouse();
 set_gfx_mode(GFX_VGA, 320, 200, 0,0);

 for(i=0; i<256; ++i)
    grey[i].r = grey[i].g = grey[i].b = i/4;

 show_mouse(screen);
 set_palette(grey);

 while( ((c = readkey()) >> 8) != KEY_Q) {
   textout_centre(screen, font, "BAR", 160, 20,155);
   alert("Bla", "Blub", "Boing", "ok", "cancel", 'o', 'c');
 }

 allegro_exit();
 return 0;
}
/* PRG END */

If you know hit a key and exit the alert-dialog by pressing a button and
then reenter the dialog you will notice that the color of the text BAR has
changed. But this only happens if the dialog is exited by using the mouse,
if you use the keyboard the color is changed to the default.
Any ideas, should i get Allegro WIP?

Ingo
