Hi Louis, thanks.
Yeah, currently the level is "INFO". I am a bit afraid of FINE/FINEST, fearing an overflow of messages that are to detailed. I had hoped for something on a higher severity - the event I am looking for is in the end an exception from the normal work. something noteworthy, not to be hidden on a Debug level. But yes, worth a try. Or maybe I just look at the source....
