If you open a window it will be placed on top of all other windows, if
you exit a menu with the mouse it normally closes, so it should work.
Maybe we should create different categories/priorities (just a numeric
value) of windows where one window can only raise to the top inside a
category.

The more I think about it the less I'm convinced about a Nasal-only
event class. There can occur many problems with (accidentally) setting
the mouse values in the wrong order, or how to get the mouse values
inside every affected element without copying to much properties around
and also thread synchronisation (if it is used) will get complicated.
How do you want to register callbacks if a custom class should be passed
as argument? Is it possible to set the value of a property node to a
custom class?
