Custom block in Header comes in between Suckerfish menu

Hi,

I wanted to add a custom block to come in the header area in the front page only. However, after I create the block and add it, the custom block appears to have come in between the suckerfish menu.

The other things that I have customized:
1. I am not using either the primary menu or the secondary menu
2. I have created my menu in suckerfish. I have also changed the background style of the suckerfish menu with my own background image (repeated-x) & hover image.

So after the customization of the suckerfish menu and addition of the custom header block, the suckerfish menu background goes right below the logo, followed by the custom header block content and then the menu links.

I use Web Developer Toolbar in FireFox3, and looks like the div styled with primarymenu is showing up, though the primary menu & secondary menu are not being used / set. Additionally, the css style for primarymenu has a padding of .5em 0 .5em .5em. So in most cases, this is causing the problem.

Please update with any solutions....
