I'm only guessing here, being a new user myself, but if the button is not large enough to fit all of the text, then it will truncate what doesn't fit. Hope this helps.If you double click the button name in the left hand panel, it allows you to type in what you want, but I'm not sure if this is such a good idea. Again, I'm only guessing, but if you change the neame on the button, it might affect the navigation action associated with that button.
