Patrice,
I guess I'm just getting too old for coding!
Delete this topic. It was my oversight.
I thought just unloading the zTrace dll by termination of the program that called it would create/update the cfg file.
I also thought I wrote a small snippit that printed GetTempPath and it did not have a trailing "\", but on further review it does,just as you said.
Sorry to have bothered you.
James
