FNCGrid does not start the drag mode

Drag with FNCGrid does not work.
DragKind = dkDrag
DragMode = dmManual

TMSFNCGrid1MouseDown(Sender: TObject; Button: TMouseButton; Shift: TShiftState; X, Y: Integer);
if button=TMouseButton.mbLeft then TMSFNCGrid1.BeginDrag(false,10);

But the drag function does not start when pressing the left mouse button and moving the mouse
The same settings in conjunction with a StringGrid work fine.

Hi, drag & drop is not enabled because the grid uses the mouse events for touch-scrolling. We'll investigate if we can expose this. drag & drop is currently limited to internal column and row dragging.
