Thanks, Alex, again. The lesson has been taught. I appreciate very much you spent time trying to help. Indeed the culprit of that infrequent infinite loops was that bound reference "item" in the printing loop. But frankly i thought that it only existed inside that loop. Apparently I was wrong and glad that it was revealed. I guess unless there is something to add here the problem is solved and subject is closed. Thanks everyone who took their time to ponder on it. I hope it was as much educational for you as it was for me.
