reports question: heading alignment

[abo fahad]

pls,

i have a report,
i have a headings at page head section.
i do align it with a controls at a details section.
it dose align good at the first page only when printing.
but it shifts little bit to the right in the other pages .
i actualy don't know who is shifting, is it the
heading or the detail.

pls, help me adjust this at all pages.
