Internet Explorer even at version 7 needs a lot of work to be able to stand next to Firefox.
When I browse my blog using Internet Explorer the page is not displayed correctly, the main column is overlapped by the sidebar and the blog title is OVER the menu.
When I browse using Firefox or Flock, everything is ok! And don’t forget to mention that Explorer sometimes CRASHES when I try to close an inactive explorer window, and instead of closing only the one I clicked , it closes ALL OPEN windows. Firefox is the leader browser for me
