Mixed mode security

Hello all,
I'm trying to modify the security setting for a local install to m ake
it mixed mode, but in the SQL Server properties window I select SQL
Server and Windows then press OK, but the window doesn't close and it
won't let me save the settings. Why is this? Can anyone help?
Thanks,
JonIt would help if you specify the version and editions
