In some cases the menu item update configuration is greyed out.
When opening or closing one or more racks, EQ, Strip e.g. , it‘s not possible to update this configuration because the menu item is greyed out. Updateing a configuration is only possible whne adding,removing, change visibility and so on, but, and this is strange, the open/close state of racks is stored.
So for me it makes more sence, to update always a configuration or not to store the rack status.
