Header keep at least 1 row
How do I make a header keep at least 1 row? I want it to not show the header if the first line will be on the next page. Otherwise I end up with the possibility of a header on the bottom of the page with no rows. I do not want to use Keep Together because that will put the whole group onto the next page.

procedure GroupHeader2OnBeforePrint(Sender: TfrxComponent);
begin
if (<force_break> <> 0) or (engine.freespace < (GroupHeader2.Height + MasterData1.Height * 2 + 1)) then
engine.newpage;
end;
where
force_break is a column in the dataset used to insert manual pagebreaks
GroupHeader2 has the column headings and the BeforePrint handler
MasterData1 has the fields
MasterData1.Height is multiplied by 2 to prevent widows (a single data line at the bottom of the page under the header); the 1 is added to allow for mathematical effects.
