Hi Riccardo. So to sum it up shortly. Just occassionally I suffer from the "good samaritan fatigue", today is one of those days. I'm tired, have plenty of my own work to get on with, and given you've already been shown a workable solution running the extra mile to go testing out your user code is beyond what I'm willing to do. I'm not paid to do this support you know.
