Got a fun one for ya guys this time.

I have a simple script attached to my gameobject. It works perfectly and all, but the problem is that if I save the scene, with the script currently attached to my gameobject, then when I turn Unity back on, the script will no longer work. If I attach it to any new game object it will work, or if I save Unity without the script attached, close it, restart it and reapply the script, the gameobject will then work correctly. But if I save and close Unity with the script on, no matter what I do when I re open it, besides closing it with the script unattached, will make the gameobject work.

Below is the quick code(so if theres a typo my apologies it is correct on my project), and any solutions to this problem would be greatly appreciated. This script is the only one that causes this problem, and it does not matter which gameobject it is attached to, they all error the same way. The button is still on the screen, it just does not function with whatever I put inside the brackets.

function OnGUI()
{
   if(GUI.RepeatButton(Rect(40,40,50,50), "Up")
      {
         transform.rotation.z = 25;  //this is what does not work anymore
      }
}

Thank You for your help
