List view and tabbing

I created a form that displays in a list view more than 20 fields.

I encountered 2 problems. One is that in designer mode the form width it is only 1500, although I defined it to be 4000; in browse mode it looks fine. How can I increase the width in designer?

The second is that I created a tab order to tab through the fields, but the scroll will not move to the right when I tab, although the fields get focused. Is there any solution for this?

To enlarge the designer veiwsize, go the application preferences, select the Designer Tab, you will see the options there.
