The magic is for the value 1 (it does not matter if written 1 or 0x1) it seems that for some magic reason that bit needs to be set or the world stops spinning or something similar. Using hex notation for bitfields is more or less the standart as it is easier to convert then decimals. -- :wq Claudio
