showing manipulator ghosted out, even when points selected.

trying to rotate several deformation points together, but i can’t get the “show manipulator” button to be selectable; it’s always ghosted-out. tried several test setups and restarting, but no solution. and i’m ensuring that the animate and transform buttons are selected, rigging tool off.

also, the “control selection mode” lasso for grabbing multiple points instead of shift/clicking never seems to work. it just wants to select other layers, or if other layers are locked, doesn’t do anything.

advice?
