    Hi again,

    looking at the zoom code I cannot see anything obvious that would stop it
    from working in either the pre or post. Zoom works in the pre and post and
    seems to work nested in functions on my system. The display can end up a
    mess or not updated when running lua as it steals all the idle time of the
    process (femme or femme view) so windows never gets to call the functions to
    redraw the display.

    Unless David or someone else spots an error I would suggest adding a
    refreshview() after the zoom command if you want to see what is
    happening.That forces a redraw of the window.

    Regards

    Robin
