However it is not clear to me how the order is established. Maybe if I know that, I can influence the order. Can you comment on that? Where can I find the code for the if_attach_internal() function? Digging into the code might also elucidate a lot of things, so I need to ask less :). Maybe I will change the code a bit to suite my wishes. If that is the case, I will inform the list and show the code. Maybe it is useful. -- Met vriendelijke groeten, With kind regards, Mit freundlichen Gruessen, De jrus wah, Wiel ************************************* W.K.
