Your Inspector is in debug mode. In the Inspector window top right corner there will be a small menu icon (next to lock icon) Click that icon and choose Normal instead of Debug.

I ask for help. How do I make a button in unity 4.2?
I saw that I had to press the left click and that something was opened to me, but nothing is missing and I do not know what to do to open that menu and make a button?
