allegro changing my color scheme...

[shadowvillian]

hi, i have a problem that has to deal with some very basic allegro code. when i use - GFX_AUTODETECT_WINDOWED -, after compiling and running it changes my the color scheme of my desktop for the duration of the program running. does anyone know how to stop it from doing this? heres some of my system specs just in case you might need them:

im running Windows 7 Home Premium 64 Bit
4 GB ram
Geforce 9500, with 1 GB memory
Intel Pentium dual core processor @ 2.0 Ghz

and heres the code:

#include <allegro.h>

int main(int argc, char *argv[])
{
    allegro_init();
    
    install_keyboard();
    
    set_gfx_mode(GFX_AUTODETECT_WINDOWED, 800, 600, 0, 0);
    
    readkey();
    
    return 0;
}

END_OF_MAIN()

I've never played with allegro, but the reason is because it is controlling the master color palette. This is an artifact of its age and interoperability with Win 2.x and DOS.

It does surprise me though. Are you running Windows in TrueColor mode? Or are you using a 256-color mode? IIRC, current versions of allegro aim to compete with SDL on modern systems.
