>[question on how to change the mouse location]

The technique you describe is an Apple No-No (tm).  However, if you really
want to change the mouse location, try this:

Procedure SetMouse(where: point);
Const
  RAWMOUSE = $82c;
  MTEMP    = $828;
  CRSRNEW  = $8ce;
Begin
  LocalToGlobal(where);
  ptrL(RAWMOUSE)^:= where;
  ptrL(MTEMP)^:= where;
  ptrB(CRSRNEW)^:= byte($01);
End;

Note again that changing the mouse location (and messing with system 
globals, for that matter) is considered hostile behavior.
