When I create a button in unity3d 5.4 the button just clicks automatic when i press play in the editor. I haven't been using unity before, so I can't say if it would happen in other versions.
First i create a script, then I attatch it to a empty gameobject. Then I press the little + sign on the OnClick() in the button properties, so I can add the gameobject with the script attached.
I have screenshots of button properties, eventSystem, Canvas, gameobject and the Script.
If anyone know what i have done wrong, please let me know. Thanks in advance.
The screenshots are in this post, since I cant post 5 images in stackoverflow: http://forum.unity3d.com/threads/unity-5-4-button-auto-clicks.426526/
