[NTG-context] structure affects protrusion

Hi, please have look at the minimal example below: Using the latest beta (20100929) with structure set to stop: protrusion works. With structure set to start: the hyphen doesn't get protruded! (but the comma still does ...?) Steffen ------- \enabletrackers[structure.tags] \setupstructure[state=stop] % <- start = no protrusion \definefontfeature[default][default] [mode=node,protrusion=quality,script=latn] \starttypescript[TheTimes] \definetypeface [TheTimes] [rm] [serif] [times] [default] \stoptypescript \usetypescript[TheTimes] \setupbodyfont[TheTimes, 12pt] \setupalign[line,block,hanging] \setuplayout [width=113mm] \starttext \showframe \input tufte \stoptext
