Hi,
Even if you put nothing besides Check_Footer folder in the main window - no other content..?
Play around with the attached form (upload while logged on in EN language) by changing the lines to be output in main window (variable under the global definitions). 51 lines should fit comfortably on one page so enough place is still left for 3 cm high footer. Anything over that number should make the footer to break to next page.
cheers
