    compiles fine...besides a shady few having to enter things twice (ie a command), and skipping over some things when enterting the info, works fine.

    I think the best thing for you to do is add this line to your main source file, just below your includes:
    #pragma comment(linker, "/subsystem:console")
    [needless explanation]You must have selected "Win32 Application" when creating your project. As you probably already know, console applications begin execution at main(), however, Windows applications begin execution at WinMain(). By selecting Win32 Application and using main() as opposed to WinMain(), the linker generates an error pertaining to the non-existant entry function. You can explictly tell the linker which type of application you're creating (console or Win32) by specifying either "/subsystem:windows" or "/subsystem:console" in your Project options (under the link tab).[/needless explanation]
