Layout of the table is screwed in FF (running on Vista).
It appears the reason is that all other browsers except for FF2 makes a linebreak at the hyphen in
<span style="text-decoration:underline">underline</span>. This forces the table to be wider in FF2. There probably isn't anything I can do about it and seeing as this is a problem uniquely belonging to that specific table I won't do anything about it. It's an internal page meant for authors (i.e. not the general public) so those few persons who are authors and using FF2 will have to live with it.
Btw, I had to switch back to FF2 to diagnose the problem. All I can say is, if you haven't upgraded to FF3 yet, do it, even when it's only an RC. Much faster, looks better and has better OS integration and handles memory more efficiently than any other browser. Anyways, this topic is not supposed to be a browser debate.
