small fix :

BEGIN_PROPERTY(CTEXTBOX_pos)

  GET_TEXT_BOX();

  if (READ_PROPERTY)
    GB.ReturnInteger(textbox->cursorPosition());
  else
    {
      unsigned int _pos = VPROP(GB_INTEGER);
      
      if (_pos > textbox->text().length())
        _pos = textbox->text().length();
 
      textbox->setCursorPosition(_pos);
    }
      
END_PROPERTY
