Thanks Tommy, OK, I have installed the I-O Assistant now. Indeed, I see a new lib dir now that was not there before. It is called " I-O Assistant " ( indeed... ). After opening this new dir I see a lib called " IIOIA.llb ". But alas, no " I-O Assistant Block.vi " in there .
Obviously I do miss something again. It is a long way to Tipperary and I feel so dumb. So, please help. Thanks. Peter.
