Hmm... I can't test in IE, but I *assume* that might be because the DOM
support of IE is incomplete or broken. Will try to find out by Googling
and checking microsoft.com and try to adjust the script if possible.
AFAIK, there is a JScript debugging facility in IE6
(Extras->Options->Internet Options->Extended???). It allows you to get
a dialog box or warning for all scripting errors. Could you please turn
this on and tell me what errors are displayed (or that none are
"application/x-ecmascript" or something more sane (we will have to
check what seems to be best), client-side scripts will stop working in
registered with IANA. Therefore using it is a violation of RFC 2045,
and because of that, of HTML 4, too, because HTML 4 has RFC 2045 as a
normative reference. XHTML 1.0 is affected as well, because it uses the
semantics of HTML 4, so we are effectively violating the XHTML 1.0 spec
at the moment. The W3C validator does not tell us that, though, because
it has some limitations regarding the parsing and handling of the
affected attribute values. It it could, it would complain loudly due to
this specs violation, I think.
We should also set a Content-Style-Type header for our pages, it's

Ahh, I'm now able to reproduce this bug. I'm debugging it, but it will
take some time... I haven't yet figured out what's causing the problem.

I'm not sure what you're referring to. If you are talking about the
lines containing "createElement": they create *elements*, not tags. So
the tags are always closed.
By the way, note that this only happens in memory. Most browsers (I
think) won't display the modified document source, but only the
original one. So you won't see the styleswitcher there at all. ;-) If
you do, and closing tags are missing, can you please send me the
relevant source snippets?

Well, I considered that a feature. :-) If you don't like it, comment out
the first occurence of "&& link.disabled" in the script and retry. If
you like that better, the invocation of updateStyleSwitcherMarkup
should also be moved after the current last line of the function that
gets assigned to window.onload , as it makes no sense to update the
style switcher on each click on one of its elements if it won't change
Please give it a try by commenting out "&& link.disabled" and tell me
what you like better. Making this an option (by setting a global
variable, for example), is no problem as well.
