When adding a marker with specific parameters, the parameters are ignored because hardcoded within the function
<DELPHI>
function TMarkers.Add(Latitude, Longitude: Double; Title, Icon: string;
Draggable, Visible, Clickable, Flat, InitialDropAnimation: Boolean; zIndex,
IconWidth, IconHeight: Integer; IconZoomWidth: Integer = -1; IconZoomHeight: Integer = -1): TMarker;
begin
Result := Add(Latitude, Longitude, Title, Icon, false {Draggable}, true {Visible}, true {Clickable}, true {Flat}, false {InitialAnimation}, 0, icDefault, IconWidth, IconHeight, IconZoomWidth, IconZoomHeight);
end;
