Hi Brian,

I checked _EggOvoid2.js from http://moi3d.com/forum/index.php?webtag=MOI&msg=10525.1 and in its event loop it is looking for Ui events of both the numeric input field and also the sliders, on line 150 of _EggOvoid2.js it has this:

if ( dlg.event == 'LValue' || dlg.event == 'BValue' || dlg.event == 'wValue' || dlg.event == 'DValue' || dlg.event == 'numpoints' || dlg.event == 'Lslider' || dlg.event == 'Bslider' || dlg.event == 'wslider' || dlg.event == 'Dslider' || dlg.event == 'Build' )

These were missing in _PowerCoenSpiralGOOD16.js, there you only were looking for UI events for the numeric input controls and not events from the sliders, that's what was different.
