Thanks mem for your kind words!
The "and" is really strange, I am used to programm in Python, so I don't mention it... No syntax error and it seems to work... Maybe the and is threaded as constant or something... Have to check.
The other suggestions I will use next time I touch the project! I like nice code, however I am a lazy guy also and this is more for recreation, like others doing puzzle games or such

PS: The ugly code also results of the experiments and tries I did before, changed much without restarting a freah project etc.
