Hi Thomas, yes this is caused by a bug in IE8 beta 2.

Currently you will need to uninstall that version of IE to make MoI work on your system. Once you uninstall it and go back to IE7 then your Done and Cancel buttons will show up again.

There is a shortcut for Done which is pushing the Enter key or using Right-click, however it will only work if there is a Done button found in the UI panel. The IE bug prevents that from happening so that shortcut won't help you in this case.
