Internet Exploder

I usually use FireFox as my default web browser, and I never tried to see how my blog looks like in Internet Explorer. But today I tried to use IE to add a new post there, and as expected from any Microsoft product, I found it messed up there. The side menu is shown at the bottom instead of the right side of the page. I tried to edit the blog template in order to fix this but it was useless as IE is a real ass hole and refuses to show the blog the way it is supposed to be shown.
