If you have a clean desktop, i mean with only "Arbeitsplatz, Netzwerk, Papierkorb" (poste de traval, réseau, corbeille), then you don't need "AERO DockBar", because this one will no find anything to populate the bar with icons.
In such a case i could display a message like this one:
"You have a neat clear desktop, "AERO DockBar" is unable to clean it up"
By the way I did not find yet the best way to detect, and use those special shortcuts matching "computer, network, tray, etc.", it is on my "todo list".
