any CSS experts in the house?

Hi all,

The biggest remaining issue before the new Mail Archive look and feel
can go mainline is a cascading style sheet (CSS) layout problem. For
example, look at the following page and expand the browser window to
maximum width.

We want the advertisment banner to "float right" and hug the right
side of the web page. Instead it hugs the right side of the
message. That's bad, because it crowds the thread navigation section
below the message body, no matter how wide the browser window is.

I'm having a lot of problems trying to figure out a way to make this
work. If there's an expert in the house who has a suggestion, please
speak up.

Cheers,
Jeff
