I recommend that the non-techies be careful in doing an upgrade from a MSMW theme to a bst-theme V1.0.1. You may want to wait for v1.0.2 after Christmas.
Additionally, there appears to be a glitch in the default data initialisation. This MSMW bug may have always been there but I have never switched a website from one MSMW theme to another before so I never noticed it. The newly installed theme may overwrite in the database a widget configured by the previous theme. If you switch back from the new bst theme to the old MSMW theme you may find one of your wdgets overridden with default text widget of links.
Sorry everyone. I'm fixing the legacy MSMW bugs as fast as I can.
