I've finally seen the light and started to program in AS3.
The thing is, I was making a menu system, a level screen, and an options screen; I test out the whole thing, and the entire screen is black (that's my background colour), so while no actual errors have shown up, my main menu isn't showing up. Since I can't actually put my code here (it would take up several pages -- you know AS3), do you know of a general cause or type of cause that would do this?
