I have no idea what to do about this, but it is not a big problem anyways. If I really need to change admin permissions while I am at the office, I just login with my mobile phone internet connection and make the changes there.
When there's a problem there's also always a cause. But sometimes they can be hard to find or very subtle. Sounds like you got one of them! Thanks for updating us Thomas.
