I just noticed a "problem" in case one wishes to move a second object when the first is moved. I'm using the various event function (mouse_down_handler, mouse_up_handler,...). When the mouse_down function is called, the status of the getSelect() method returns the previous value and not the currently clicked object. I think that getSelect() gets updated after the call "return, 1" of the mouse_down_handler function. Kind of a pity, because tracking of clicked objects is somewhat more complicated, but not impossible.
