if(ObjectGetInteger(0,"Label",OBJPROP_SELECTED) == true)

      {

      ObjectSetInteger(0,"Label",OBJPROP_XDISTANCE,(int)lparam);

      ObjectSetInteger(0,"Label",OBJPROP_YDISTANCE,(int)dparam);

      }

I want to link with the mouse cursor when OBJ_BITMAP_LABEL is selected. However, it doesn't work unless the tick comes. Nothing is written in OnCalculate. I wonder why.
