Well, it is actually the DIVs in the alternating rows for the listings.
In FF2, I get about 3px overflow. In IE 6, it is fine.
But in IE6, I get about 3px of whitespace in the narrow DIV, aligned vertically with the section I get the overflow for the listings in FF.
Hope that makes sense.
Thanks for the tip on the form not displaying inline. I got that fixed up. 🙂
edit
It's like the container DIV shifts 3px from FF to IE ...
