Shock: all windows below

Hello, Today in the early morning I am very scared: I come out of the house and all the windows have gone down. Fortunately it only a little potted. Important rule would have been a problem. It is also stupid, because right next to it is a pub. But apparently nobody noticed. What can that be? This is really a huge problem! I often have valuables in the car, and besides, I do not want the car to swim at some point. 2003 GP0 Greeting, Tobi.
