[Plugin: Contact Form 7] Resizing Entry Field

Hi there,

I am trying to add a small, one-field “Mailing List” contact form in the footer area of a Genesis theme site. I can add the form to the left side widget area, but when I try to move it to the center, it just disappears. I am thinking there might be a size restriction, so is there anyway to resize the width of the entry field on a contact form?

Thanks
