Howdy,

Thanks Ross. I hadn't thought about that sort of thing happening.

I also use the latexmk engines for most jobs that require multiple runs of (pdf/xe)latex with possible runs of bibtex (or biber used with the biblatex package) and/or makeindex in between. I think that only re-displays the pdf if it completes all operations so you don't see the movement between the runs.

Good Luck,
