* when hiding/deleting objects. Also if an object is entered
* multiple times, and its status changed each time, when the
* Q is handled, we get wrong status.
*
* The other way to handle the interaction is to process object
* Q as soon as the status of the object is changed. This is

* preceeded by a redraw (say mouse release on button), and due to
* the X buffering mechnism, the redraw probably not get shown yet
