While logging into a domain and the windows user account is set as power-user or Administrator then everything is fine. If the user logging is a  restricted user (Windows users group) then I get the following error:

  Access to the registry key 'HKEY_LOCAL_MACHINE\Software\MicroFour\StrataFrame\Security\LoginForm' is denied.

The only way at the moment to get everyone up and running is to change there access level in windows. Is this by design or a bug?

Thanks
