Screen Formatting Changes when I am on another FB Page

Ayman,
The "Switch" box is normal and meant to be shown whenever you are "Using Facebook as a Page" instead of a personal profile. Page's can't Like or leave Comments on things like users.

As for the look, that's unfortunately what Facebook does. It's a really ugly view, we'll agree. On sites with a white background, it generally looks much better because the width of that white area is hidden. There's really not an easy or good way to fix that. You can implement some CSS that would make the area smaller, however, it would work for the 'normal' view as well, which means your comment box area would be shrunk even when you're using a normal user profile. There isn't any way for JFBConnect to detect if the user is logged into Facebook as a Page, a user profile, or even logged in at all in most cases, which means we can't just target the Page mode with some fixes.

I hope that helps explain. If you have any feedback or suggestions, please let us know.

Thanks,
Alex
