Original Post
So, I'm trying to make a little console object, but whenever I toggle for it to be visible, my program shuts down. I get no errors, but I simply don't know what the problem is. I'm really sorry about the posting problems thing. This is probably something really dumb again, but I can't seem to find the problem. Here's my code: main.cpp engine.h engine.cpp video.h video.cpp Anyway, I'm still fairly new to programming considering the experience everyone else here has. I think the problem is most likely found in cConsole::Render() [Edited by - FernandoLujan on January 7, 2007 12:18:54 AM]
