Hi hgibson,
Can you ensure that you've optimized your browser properly? Steps on how to optimize IE is provided in this link:
How to optimize your Internet Explorer browser
HTTP Version: Some folks have reported that altering the version of HTML that IE uses helps resolve their issue. In IE: Tools, Internet Options Advanced, locate the entry HTTP 1.1 settings and uncheck Use HTTP 1.1. You may have to exit and reload IE for the change to take effect.
If that doesn't fix it, post your Windows Live Hotmail address so we can check it out.
Thanks
