Did you ever tried to use a Dojo TabContainer (tabbed table) in a non-trivial page with Internet Explorer?

It basically works. But the Internet Explorer is so damn slow that you can see the single tabs below eachother while the page is being loaded, and only after loading they are rendered in a tabbed table. That's not an issue in other browsers like Firefox or Chrome.

BTW the same problem occurs when you try to change stuff like CSS classes with Dojo's dojo.addOnLoad() method... works perfectly in any modern browser, in Internet Explorer, you see the changes happen on the page because the Internet Explorer is so slow.

And it's the very same even in the most recent Internet Explorer 9!  U N B E L I E V A B L E !

It's really a total mistery to me why a company like Microsoft ist not able to create a modern, useful browser.
