Your display did change. You can see that the border is gone from the tabs.
The page template you are using is too narrow. You need to make it wider or adjust the css for the flytabs theme to fit in the width that you are using.
The same css member I told you about before can be used to make the entire theme narrower, but it will require moving some things around with the css and probably changing some sizes...
You have to experiment and see what works.
