Okay, in addition to my former message, a NODEFAULT is only half the work. I changed to:

LPARAMETERS;
 tnDirection,;
 tnShift,;
 tnXCoord,;
 tnYCoord

THIS.PARENT.MOUSEWHEEL(m.tnDirection,m.tnShift,m.tnXCoord,m.tnYCoord)

NODEFAULT

Then the scroll of the column - or whatever container - will run.
