[NTG-context] Can't set typescript

I'm trying this small test: %%%%% \enableregime[utf] \usetypescriptfile[type-xtx] \usetypescript[gentium] \setupbodyfont[gentium] \starttext \showbodyfont \stoptext %%%%% It's supposed to select 'gentium' as typeface, but the chart shown by 'showbodyfont' says I'm using 'modern'. Am I missing something? I'm using minimal install, updated yesterday (although I have this problem for at least two weeks). Thanks, Maurício
