Hi Brian, my guess is that something did not go quite right with the IE7 reinstall...

MoI uses a piece of IE to display those UI panes - something is now not functioning properly in the IE system on your Windows installation.

Was there something going wrong on your system that required an IE7 re-install? Was the re-install because you had the IE8 beta release installed on your system?

It's possible that may be difficult to remove, you may need to use System Restore to try and go back.
