5.01 Broke GUI Button?

I'm following a tutorial on YouTube and it said to add the UI - Button component to the image, which I had done before, but now in 5.01 it is not there.

I found it strange, so decided to just use a regular button for what I wanted to do and make it a prefab and go.

However, whenever I make the button a prefab, the Unity Script will not load when the game is run.

Is anyone else having this problem?

 

I too having problem with New UI;s Button, Whenever I click on button its not click-able , but when I take cursor slightly above the button and click, it gets clicked.

I guess Something like offset problem occurring here.
