GUITextures and windows and such won't fade when fading screen to black

I have some issues when fading my screen to black using a GUITexture. My scene fades as it should, but all the GUI-elements stays visible… Is there a way to put my GUITexture on top of everything on the screen before fading the screen out to black?

Sorry for bumping this…

Isn’t there anyone who can help me out with this? To clarify my problem:
I have a main menu in my game, which is a 3D scene showing a part of a level, I have my game logo in the top left corner and the menu on the right… Before I fade the screen IN upon starting the game the game logo and menu is visible and my background level is fading in as it should from black. I want the logo and GUI menu to also fade in from black. But it seems all GUI elements is on top of everything, except for my 1x1px black texture, which is only covering my “level”…

There must be a way to fix this, right?

Try GUI.color.a = alpha;
