browse lookup - allowable number of lines?

[John Esak]

How come putting the value "20" for Lines: in the Browse Window section of
the lookup wizard causes a "Value 20 out of range" error. Yet if I build the
browse myself (which I almost always do these days) and put 20 there. It
passes syntax check and runs perfectly... giving me a browse window that
fills the entire screen which is exactly what I want.
