CFDocument- Output is cutting lines

The PDF document being produced is perfect on all 3 pages except for the first line of every pages (other than P1) is being cut "horizontally"... the line is there but I can only see the bottom/lower half of it.... as if the space reserve for the header or margin was overwriting the top portion of the text. I tried changing the size of the topmargin with no success; so I went back to using the default value and the problem is still there (no surprise).

I am using Adobe PDF Pro V6 so, thinking it may have to do with the Adobe version (not necessarely your average user) I went to a workstation that uses Adobe Reader V7 but same result!!!???

Any help would be much appreciated.
Thanks,
