Re: [Libgdn-discuss] Wierd Behavior with ConsoleStream

[Lin X. <ris...@ho...>]

If you define the console stream in global scope, it will try to instaniate 
the console before main.
:)
What do you think will happen? I'm actually suprised it even runs..
actually, the console should work.
How do you mean the colors are wrong?
Are there no colors?
Are the colors the wrong colors?
