>>>I think I understand your point now. Even though I have one column I can change the width. And in fact if I change the width in the properties, the Detail band becomes wider. The only possible "problem" is that mysterious vertical line is still visible but now outside (to the right) of the report Detail band. I hope it will not message up in the print out.

>I can't seem to figure how the page setup would cause the problem. Attached is the image where you will see a vertical line to the right of the Detail band. I have never seen this type of line in any other report and I can't get rid of it or understand what it is.

I see you found that there is something related. :) The problem is I remember there is some connection, but can't remember the precise one. Some stuff gets placed outside the boundaries. Normal I grow the papersize to something like A3 (common here is A4 that's close to your standards) so it catches all. I also believe that there is something with multi columns and the gap betweeen. But this is all out of the hip.
