This is an issue that has just started ever since last week. Both another designer and myself have found that for the past couple of days, whenever we are in a model and either make an edit to an OBM object or rename an object, the Explorer collapses and you need to expand out all of the menus again. This is a severe annoyance when you consider that we are renaming all barriers/bearings/decks etc. Is there a way to prevent that from happening? Will there ever be a function to expand all or collapse all in the Explorer?
