Given that in any browser the page is an accessibility train wreck - illegibly undersized fonts, color contrasts (or more specifically lack therin) making the text eye-strain hell, I shudder to even peek under the hood for problems like this...
Where I see endless IE conditionals on a layout not doing anything fancy enough to warrant their use, SIFR nonsense further explaining the illegible text, endless DIV for nothing, clearing DIV like it's still 1998, pointless classes (first_line for example), pointless ID's and classes, spans for nothing, nonsensical heading orders (like the H5 with no preceeding headings, h1 doing h2's job, h2 doing small inside that h2's job), attributes that have no business even being in modern markup (target,cellpadding,cellspacing), invalid/improper form structures, image maps for christmas only knows what... and thirteen validation errors. (and a hell of a lot more errors if one were to switch it to a MODERN doctype instead of slapping a Tranny one on HTML 3.2)
It's not exactly shocking I'm seeing four different appearances in four different browsers! Layout issues? It's begging for it.
Baffling? Uhm... no. Throw it out and start over, there's NOTHING worth trying to salvage there.
