issue with balanced columns

issue with balanced columns

[Pablo Rodriguez]

Dear list,

I have the following sample:

    \showframe
    \showgrid

    \setuplanguage[agr][patterns={agr, us}]
    \mainlanguage[agr]

    \definepapersize[HippPaper][width=6in, height=9in]
    \setuppapersize[HippPaper]

    \setupbodyfont[dejavu, 13pt]

    \setupbodyfontenvironment[default][em=italic, x=.95]

    \setupregister[index]
        [language=gr,
         indicator=no,
         before=,
         after=,
         distance=3ex,
         textstyle=\tfx,
         pagenumber=no,
         n=2,
         align={verybroad, hz,hanging},
         method={zm,zc}]

    \starttext
    \mbox{}
    \index{ἀδελφός, ὁ: brother}
    \index{ἀδικίη, ἡ: wrongdoing, injustice}
    \index{ἀκρόησις, –ιος, ἡ: hearing, listening}
    \index{ἄνευ: without (\char43\ gen.)}
    \index{ἄρρην, –εν: male}
    \index{γένος, –εος, τό: race, family}
    \index{δήλησις, –ιος, ἡ: ruin, bane}
    \index{διαίτημα, –ατος, τό: regimen, diet}
    \index{ἐπικρίνω: decide, consider}
    \index{ἰητρικός, –ή, –όν: of a physician, medical}
    \index{κάμνω: be sick, suffer from illness}
    \index{λοιπός, –ή, –όν: remaining, rest}
    \index{μάθησις, –ιος, ἡ: learning}
    \index{μαθητής, –οῦ, ὁ: learner, pupil}
    \index{μανθάνω: learn}
    \index{μισθός, ὁ: wages, pay, hire}
    \index{νόμος, ὁ: custom, law}
    \index{ὁρκίζω: bind by oath}
    \index{υἱός, ὁ: son}
    \index{χρέομαι: use}
    \index{ὠφέλειη, ἡ: help, aid, benefit}
    \placeindex
    \stoptext

Although colums are balanced, I get unbalanced columns.

Is there a command that prevents the wrong balanced columns?

Many thanks for your help,

Pablo
