All,

We have a number of Edd/dm displays which are related hierarchically, such that a single 'main' display can
invoke a number of subordinate displays, each of which can invoke other displays, and so on.

To move down the tree a 'related display' button is used, which creates the new display, moving up the tree is
achieved by 'quitting' from the current display.

It would be far more intuitive, if a button could be used to move up through the tree, the button would
either quit from the current display or make the parent display the current one, however I cannot find a
mechanism to do this.

Has anyone used these displays in this fashion, or could anyone tell me how to either:

1	Use a button to cause a 'quit' from the current display.

or better still:

2	Use the 'related display' button to make a display which is already running, the current display.

Thanks in advance.
