In IE11 running through Remote Desktop Services to a Server 2008 R2 server some user sessions have empty fields selections from the F12 Developer Tools option.  The fields are found under the Emulation icon.  Not sure why it only happens with some users and not others connected onto the same server.

Same problem here with Windows 7 Enterprise x64. When started with "run as administrator" the dropdowns are filled.
