For me, the width of the "sclogin-joomla-login horizontal pull-left" div in Chrome was computed to ~285px. In IE for me, the text links were right next to the Login button, not underneath and to the right like your screenshot. I also inspected and there was no width set. When I added the same width style, the links were forced under. So my suggestion is to find what is forcing the width to that size for Chrome or adding a width to the div.
