ok, im in options menu, and when the user selects back to main, it goes back to mainMenu() so i use some variable, cause someone says thatcalling functions directly from other functions, im gonna run ou tof stack memory so i tried this but when i hit back to main, it just freezes i want to be able to when the suer hits back to main, it just goes back to mainMenu() cleanly, and not with all these probs |

Uhm, why aren't you doing what we told you in #Allegro (make the menu functions return a value, then act on that value, spawning other menus as necessary)? |
