As this seems to be a stumbling block for so many and I can see complaints from users upgrading stretching into my future.
The choices validation will (from CI build #1223), when the system colour options are all configured to black, simply reset them back to defaults. This does mean that in future noone will be able to set all system colours to black intentionaly, but as that seems a daft thing to do anyway... -- Regards Vincent http://www.kyllikki.org/
