Re: Re: Re: typesetting fractions


One can affect page breaks by adjusting the spacing between cells. This 
is incredibly tedious to do with the Options Inspector, but there is a 
palette named "Glue" (find it at MathSource) that lets you select a 
whole page of heterogeneous cells and shrink or expand the between-cell 
spacings. I've used it extensively, and it cuts the time needed to 
page-break a 50 page document from several hours down to about an hour 
(for me anyway---I'm rather picky).
