Dreamweaver: Locking layers in place

This is a toughie. I got an extension for DW that lets me add a dhtml scrollable area on my static page. It looks good @ 1024x768 but on 800x600 it is in a different location. Its “fixed” but how do I make it relative to the rest of the page? I have a table with a layer then the scrollable area in that. I really hope someone can help me with this.

Could we have a look at it somewhere, i didn’t quite get what you want? (forgot all my html since i started using flash…)
