Magento checkout broken in IE9 and IE8 for that matter
When testing our checkout in Magento we ran into this strange error with IE9 when opening the following page (maybe first select a product)
http://shirtsofholland.com/checkout/onepage/
SAME AS: http://www.magentocommerce.com/boards/viewthread/267307/
Any help appreciated, debugged alotta things. No solution yet
What happened was that the plugin Crius Skipstep (hiding whole login section) was breaking the layout code.
We resolved by stopping the extension & logging an issue at their site

Thanks for your answer philwinkle (I am sure this works for many other cases!)
