State object error when implementing Matrix4x4.TRS solution to set resolution independence

Question

I'm trying to set resolution independence by setting my GUI.matrix via the following code:

private float nativeHorizontal = 800.0f; private float nativeVertical = 600.0f;

void Start() {
    // set resolution independence
    GUI.matrix = Matrix4x4.TRS( Vector3.zero, Quaternion.identity, new Vector3(1.0f*Screen.width / nativeHorizontal, 1.0f*Screen.height / nativeVertical, 1.0f));
}

Weird thing is, I get the following runtime error:

InvalidOperationException: Operation is not valid due to the current state of the object System.Collections.Stack.Peek ()

I've tried searching for Answers (pardon the pun), but I can't find anything. I don't understand how there could be a "stack" error when call the TRS function. Can anybody enlighten me on this?

Thanks,

Dendro

The problem is probably that the GUI object is only accessible during the OnGUI function. So probably you would have to move your code from Start() to OnGUI().
