Well, that file *is* still working correctly here, whether <sup>, <SUP>
or CSS. 

The HTML version should be working if you haven't redefined <sup>
somewhere. Is there a chance that you have either included it in a
<style> or loaded (a) CSS (file) which has redefined <sup> ? It sounds
unlikely.

Perhaps your file !NetSurf.Resources.CSS has somehow been changed or been
corrupted? NetSurf's default <sup> is defined as:
sup { vertical-align: super; font-size: .83em; }

(which is interesting because other browsers use
sup { vertical-align: super; font-size:smaller; }
)

Though you don't think you use CSS it is how many of the <> directives
are defined in the browser so you ARE using CSS, whether you like it or
not.  ;-)

I think I would download a fresh NetSurf and create a fresh install. i.e.
don't copy it over the old one, create a new one.

Alternatively, include the <style>...</style> from the above file in your
<head>..</head> and use the <span..>...</span> it uses.
