As I said before, some of the Wizard Themes and Layouts can be made to automatically adjust to different screen sizes. Unfortunately, the one you have picked is one that can't be adjusted easily. That particular Theme is table based, and the content areas have very specific widths. Some are defined in the HTML and some in the CSS. It's possible that it could be done, but it would take a lot of work and it's unknown whether the graphics are flexible enough to let it work well.
