Question
TWiki (TWiki20030201.zip) pages crash IE 6.0. If I start with a fresh browser process and look at TWikiPreferences, then hitFind (CTRL-f) and search for
asdfasdf (which is nowhere on the page), IE 6.0 crashes. Strictly speaking, this of course has nothing to do with TWiki, but it is annoying that searching on many TWiki pages crashes the browser including all the other windows that may be open at the time.
http://twiki.org/cgi-bin/view/TWiki/TWikiPreferences
also crashes my IE6.0 so it has nothing to do with my setup.
I looked in BrowserIssues, but did not find anything similar to this topic.
I found a workaround:
In INSTALLDIR/templates/twiki.tmpl, Change the DOCTYPE and <html> tag from:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">to
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html>There already is a XhtmlConsideredHarmful topic here, and I don't claim to know anything about XHTML, other than it crashes IE6.0 (but not Mozilla....) There may be and probably is a zillion other ways to work around this IE6.0 problem, but I haven't looked into that. My DOCTYPE workaround seems to work for me.

Answer
I am wondering if this is a common problem with IE, although I have not heard of this. The TWiki templates use XHTML 1.0 Transitional as defined in http://www.w3.org/TR/xhtml1/. The annotaed DTD is at http://www.w3.org/TR/xhtml1/dtds.html#a_dtd_XHTML-1.0-Transitional
A TWiki page starts with:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
Oh, I just realize, there is one small difference: The DTD also defines:
<?xml version="1.0"?>
at the very beginning of the page (which is missing in the TWiki templates for HTML compatibility). Does it solve the problem if you add this to the original TWiki templates?
