This field is on a report set to Stretch with Overflow. When I set a string into this field of about 1340 characters or more the report prints many, many pages (I usually stop after about 30-40). If I set the string of less than 1340 (approx) the report prints on one page. What I don't understand is why it goes from 1 page to many, many. Logically I could see it going from 1 to 2 pages but why to so many?

Thank you very much again. This was it; the fact that I had the entire report in the header. Originally this report was supposed to print only a couple of lines (it is actually a copy of another very similar report). And today I added stuff to this report; hence the long string. And it must have been causing what you said "loop situation." I moved the field to the Details band and works fine now.
