>You should look at IE10. Totally different than IE6.
I think it was IE8 when I last had to use it (because the bank here had software based on an ActiveX - among other stupid rules they had, solved by closing the account within three months).
Luckily, I'm not doing the web app anymore, it's been passed to a younger programmer, so looking at those only-for-testing browsers, like Chrome, Konqueror, IE and whatever runs on phones are something I don't have to do :).
