OnMouseDown problem in Windows Phone. Any solution?

Hello and thank you for reading this post:

I have a simple image in the game with a boxcolider component. I have a script added to this image with the following code:

Code (CSharp):

1. void OnMouseDown () {
2. Debug.log ("You touched the object");
3. Camera.main.backgroundColor = Color.Magenta;
4. }

When building my project to Windows Phone 8, shows the following warning:

Once the project is loaded into Unity, requests file: mouse.cs.
Once "fixed" this problem manually, the project finally loaded into the emulator, but not working.

Any solution to my code?, Could use a touch event, but only when I touch this object?.

Thanks and a greeting.

 

I was beating my head against the wall too.
