Menu Bars Vertical Movement

Hi -

Can I get the menu bars to automatically move up or down when I change another element? I've changed (resized, adjusted margins) my logo at the top of the page I'm designing. When I refresh the screen the logo infringes on or pushes part the menu bars down - but only part of the bars (see attachment). How do I move the menu bars up and down?

Also, is there a good reference source for using Athualpa and answering these types of questions so I don't have to keep bothering the forum?

Thanks!
