[NTG-context] get rid of placefigure and startcombination captions

Hello, Another urgent problem: how to get rid of placefigure and startcombination captions altogether? When I use the following, I get too much wasted space after the illustration. \placefigure [fit] {none} {\startcombination[4*1] {\externalfigure[serg1][width=4cm]} {} {\externalfigure[serg2][width=4cm]} {} {\externalfigure[serg3][width=4cm]} {} {\externalfigure[serg4][width=4cm]} {} \stopcombination} Best, Vyatcheslav
