GUI.Button not visible

This is really stupid I know, but I can not see GUI buttons. I am using a simple script from the manual and they do not show up in my project. Any ideas?

function OnGUI () {
	// Make a background box
	GUI.Box (Rect (10,10,100,90), "Loader Menu");

	// Make the first button. If it is pressed, Application.Loadlevel (1) will be executed
	if (GUI.Button (Rect (20,40,80,20), "Level 1")) {
		Application.LoadLevel (1);
	}

	// Make the second button.
	if (GUI.Button (Rect (20,70,80,20), "Level 2")) {
		Application.LoadLevel (2);
	}
}

Do you mean that they dont show up in editor? If thats the case, its normal - unless specifically told to do otherwise, Unity does not execute normal game scripts in the editor.

No, they won’t show up in the game view even playing the game.

I just realized that it is project related. If I open a new project it works as it should. Just in my project they will not show up. I would really like to keep my project and not start over.

Are you getting any error messages when the script fails?
