[NTG-context] bad kerning with Garamond

Hi, I've copied the files GARA.TTF, GARABD.TTF and GARAIT.TTF (Monotype Garamond) to the fonts directory and then regenerated the database. This is my test-file: --8<---------------cut here---------------start------------->8--- \usemodule[simplefonts] \setmainfont[garamond] \starttext \input tufte \it \input tufte \bf \input tufte \stoptext --8<---------------cut here---------------end--------------->8--- The output is here: http://pmrb.free.fr/tmp/test.pdf and it's very ugly. How could I get better results please? TIA for any help! -- Peter
