Does anyone know of a way to use the first method described here to cover the MySpace URL box without it increasing the height of the table?

I'm currently using the 2nd method, but am getting annoyed with the page changing itself all the time. I constantly have to keep adjusting the coordinates of the div.
Anytime I line it up right, the page moves itself again. Either the links above the ad space out or the space above my caption disappears/reappears as is the case this time: See for yourself. Notice how the floating MySpace URL box is too low, even though it was lined up perfectly 2 days ago. It is for this reason that I'd like to switch to the 1st method. It's just a shame I can't get it to work without stretching the box vertically. Any help getting either method to work unconditionally would be greatly appreciated.

EDIT: Updated profile, so it's different now
