I don't think it was that, I think the problem was in the standard P5 default. Read this from the P5 SR3 read me.... - The Service Release 3 installer provides some small corrections to the default user interface preferences. In order to make the changes effective, please delete all UI Prefs XML files in Runtime/Prefs which are not prefixed with the word 'Default'. If you want to stick with your current user interface preferences, do not delete these files.
