I apologize, but I’m honestly not seeing the issues you’re describing. Your website works great for me in all web browsers.
Specifically, here is what your site looks like for me in IE9: http://picturestack.com/527/19/m7mywcamtlsbr.png
Are you sure you didn’t accidentally turn on compatibility mode with your IE9 browser? I just turned it on, and saw the container shift to the left. When you turn on compatibility mode, it means you’re viewing your site in a simulated IE7.
