I just downloaded allegro and it come with examples...I compiled one example(exflame.c) and it doesn't work,the program purpose is to demonstrates how to write directly to video memory.
I linked the library with directx 7 and read once that window vista has some problem with direct draw...
Is the problem related to vista incompatibility with directx 7?
