Demo (modified page of History/Remote - jQuery plugin) is here - http://www.zone.ee/ofilez/js/xendi.html (free hosting, click skip advertising) (also you can get directory listing at http://www.zone.ee/ofilez/js/ )
Click the link "Load Chapter 1". (it loads http://www.zone.ee/ofilez/js/chapter-1.html using jQuery ajax). chapter-1.html contains two tabs plugins: idTabs and "jQuery UI Tabs aka Tabs 3". In FF2, Safari and Opera (on WinXP) - both plugins with no problem IE6 - "jQuery UI Tabs aka Tabs 3" - ok, idTabs - problem I hope this helps
