Almost impossible to say without trying. Could be simple rounding error,
as you do pixel perfect with other units. Try smaller width on right
floated stuff, as it looks it is too wide.

Does the following link help?

I've downloaded Opera6 and I'm trying to recreate the problem with a basic
layout but so far everything looks exactly as expected. Humph! Damned
Opera - never breaks when you want it to!

Found it! (I think)

Older/some(?) versions of Opera didn't clip overflowed content properly. It
may not have been displayed but it did affect layout. The line height in
#topnav is not necessary. I downloaded a copy of your site, removed the
lineheight from the stylesheet and your page then displayed correctly.

Here is the offending code in your stylesheet.
(best viewed in monospace font)

#topnav { width: 780px;
         height: 30px;
HERE----> line-height: 30px;
         background: #D5E7FA url(topnav_b.gif) repeat-x;
         border-right: 1px solid #FFFFFF;
         border-bottom: 1px solid #74A5D7;
         margin: 0;
         padding: 0;
       }
