Exactly; but won't the browser come up with 500.5px, both for the 
#frame DIV and for the background GIF? Why then place the GIF at 500 
and the DIV at 501?

Thanks for the ideas. Will implement them to the best of my ability :)

Forgive me for this. We are working with Macromedia Contribute as a 
CMS, and the complicated set-up allows them to choose their own "theme" 
for each page as they wish, simply by changing the appropriate 
style-sheet.

Thanks Gunlaug for taking the time to dig into my code and come up with 
your helpful suggestions. Much appreciated.
