When I recall correctly the initial bug was related to DWC, that is why am reporting this here again. On some occastions when pressing a button on the PanelDue the message related to this is displayed only, whereas the PanelDue shows only "busy"
This is pretty annoying when you sit in front of the printer and don't what the printer is waiting for. Especially when the computer is in the next room...
This is the ressurection of an older bug that was fixed.
