Hi and thanks, this is perfect - I am already warming up my soldering iron...! Don't worry about the lingo, norwegian works just fine....

The firts links page you sent me didn't work, probably because I use Explorer with all the @#4!!!€ pop-up-blockers, I'll install a free-ware browser and look again. Thanks a lot for your fast help, I'll be back with a running report!
Regards from sunny Denmark (21 degrees centigrade and a fresh wind...)
