Again:
I would code in the printpage event some thing like:
if pagenumber = 1 then
thisModify("DataWindow.Header..Height='100'")
thisModify("DataWindow.Header.group 1.Height='0'")
else
thisModify("DataWindow.Header..Height='0'")
thisModify("DataWindow.Header.group 1.Height='100'")
end if
That makes you print the header on the first page and header of group 1 on all the other pages.
