I am having trouble reverting to the default open LCA viewing screen where the navigation pane is on the left and any process/flow opens on the right (a split screen). When I open a process or flow from the navigation pane now, it shares the same window as the navigation pane and the view is no longer split. This happened after I detached the navigation pane (right click, detach) from the main openLCA screen. Any ideas on how to revert back to the original split view?
