I am having a very odd issue. I tracked it down to trying a very simple:

using UnityEngine; using System.Collections;

public class Mouse_SceneClick : MonoBehaviour {

// Use this for initialization
void Start () {

}

// Update is called once per frame
void Update () {

    if (Input.GetMouseButtonDown(0))
    {
        Debug.Log("Clicked at " + Input.mousePosition);
    }
}

}

No matter how or where I move the mouse in the window the position always comes out exactly the same

Clicked at (196.0, 242.0, 0.0) UnityEngine.Debug:Log(Object) Mouse_SceneClick:Update() (at Assets\Scripts_HHT\Interface\Mouse_SceneClick.cs:16)

It detects the mouse and the script or it would not be detecting clicking, but beyond that I cannot get any usable information. I am using Unity 2.5 (I understand the patch dealt with a related issue but that was for Mac, I am on a PC - Dell XPS if it makes a difference). I can't upgrade to 2.6 until tomorrow since we have an investor lined up and this is the last feature I am trying to squeeze in - I don't want to risk breaking my system right before tomorrow if I don't have to.

So... anyone have a similar issue by chance that they found a resolution to? Am I missing something incredibly silly and obvious?
