Superfish causing content jump (updated)

Superfish causing content jump (updated)

I added Superfish to a site I have, trying to make the drop down menus compatible with touch screen devices.  The problem I'm having is when, with a mouse, you roll over the menu tabs that have submenus the section below jumps.  This doesn't occur in the same page that doesn't have Superfish added to it. 

You can see what I mean by looking at this Superfish page and this same page without Superfish. The menu tabs About and Contact have submenus and as you roll your mouse across them, the area below them jumps around.

Any help would be appreciated. I'm very new to this so if you can make your suggestions easy to understand I would really appreciate it. 

Thank you.

EDIT:  I just realized I had the included the wrong link as the example of the page without Superfish.  Arrgghh!  Sorry.  I've corrected the second link now.  

If anyone can test the pages using a mouse and give me any idea why the Superfish page jumps and the other page doesn't when rolling a mouse over the menu tabs, I would really appreciate it.  Thanks.
