trouble with button size

I've created a button which is pinned to a sprite (to create a context menu).

In the layout I make the button width 165 and the grey sprite is 175 in width;

however when I run the game up the button is now wider than the sprite;

Any ideas on what I've done wrong?

Buttons are actually drawn by the browser, which can override C2s values. They are good for quick and easy button objects, but if you need precise alignment, you'll need to do your own buttons as a Sprite or 9-patch.

thanks for the explanation blackhornet

I always suggest everyone to use sprite buttons.

Well said Doc
