gTooltip issue when customizing theme ...

I'm having an issue when customizing my theme (to use with a Rapidweaver theme). The problem is that when I hover over an item during a move or delete, the image shows partially within the header. I'm wondering if I can fix this with a css change or if I need to do something with the theme template.

EDIT: Fixed my issue. Rapidweaver styles.css had: #container position: relative; and I changed this to position: none; and my issue is resolved.
